+The `Object.assign()` method is used to 1) add properties and values to an existing object, 2) make a new copy of an existing object, or 3) combine multiple existing objects into a single object. The `Object.assign()` method requires one targetObject as a parameter and can accept an unlimited number of sourceObjects as additional parameters.
+
+Important to note here is that the targetObject parameter will always be modified. If that parameter points to an existing object, then that object will be both modified and copied. If, however, you wish to create a copy of an object without modifying that original object, you can pass an empty object `{}` as the first (or targetObject) parameter and the object to be copied as the second (or sourceObject) parameter.
+
+If objects passed as parameters into `Object.assign()` share the same properties (or keys), property values that come later in the parameters list will overwrite those which came earlier. 
+
+**Syntax**
+
+```javascript
+Object.assign(targetObject, ...sourceObject)
+```
+**Return Value**
+
+`Object.assign()` returns the targetObject.
+
+**Examples**
+
+_Modifying and Copying targetObject_
+```javascript
+let obj = {name: 'Dave', age: 30};
+
+let objCopy = Object.assign(obj, {coder: true});
+
+console.log(obj); // returns { name: 'Dave', age: 30, coder: true }
+console.log(objCopy); // returns { name: 'Dave', age: 30, coder: true }
+```
+
+_Copying targetObject Without Modification_
+```javascript
+let obj = {name: 'Dave', age: 30};
+
+let objCopy = Object.assign({}, obj, {coder: true});
+
+console.log(obj); // returns { name: 'Dave', age: 30 }
+console.log(objCopy); // returns { name: 'Dave', age: 30, coder: true }
+```
+
+_Objects With Same Properties_
+```javascript
+let obj = {name: 'Dave', age: 30, favoriteColor: 'blue'};
+
+let objCopy = Object.assign({}, obj, {coder: true, favoriteColor: 'red'});
+
+console.log(obj); // returns { name: 'Dave', age: 30, favoriteColor: 'blue' }
+console.log(objCopy); // { name: 'Dave', age: 30, favoriteColor: 'red', coder: true }
+```

+title: Object Destructuring
+---
+
+# Object Destructuring
+
+Destructuring is a convenient way of extracting multiple values from data stored in Objects. It can be used in locations that receive data (such as the left-hand side of an assignment). This feature is introduced in `ECMAScript 6`.
+
+How to extract the values is specified via patterns (read on for examples).
+
+### Basic assignment
+
+```
+var userInfo = {name: 'neel', age: 22};
+var {name, age} = userInfo;
+
+console.log(name); // neel
+console.log(age); // 22
+```
+
+### Assignment without declaration
+A variable can be assigned its value with destructuring separate from its declaration.
+
+```
+var name, age;
+
+({name, age} = {name: 'neel', age: 22});
+```
+
+> The `( .. )` around the assignment statement is required syntax when using object literal destructuring assignment without a declaration.
+
+> `{name, age} = {name: 'neel', age: 22}` is not valid stand-alone syntax, as the `{name, age}` on the left-hand side is considered a block and not an object literal.
+
+> However, `({name, age} = {name: 'neel', age: 22})` is valid, as is `var {name, age} = {name: 'neel', age: 22}`
+
+### Assigning to new variable names
+A property can be unpacked from an object and assigned to a variable with a different name than the object property.
+
+```
+var userInfo = {a: 'neel', b: 22};
+var {a: name, b: bar} = userInfo;
+ 
+console.log(name); // neel 
+console.log(bar); // 22
+```
+
+### Default values
+A variable can be assigned a default, in the case that the value unpacked from the object is `undefined`.
+
+```
+var {name = 'ananonumys', age = 20} = {name: 'neel'};
+
+console.log(name); // neel
+console.log(age); // 20
+```
+
+### Assigning to new variables names and providing default values
+A property can be both 
+1. unpacked from an object and assigned to a variable with a different name and 
+2. assigned a default value in case the unpacked value is `undefined`.
+
+```
+var {a:name = 'ananonumys', b:age = 20} = {age: 22};
+
+console.log(name); // ananonumys
+console.log(age); // 22
+```
+
+### Setting a function parameter's default value
+
+#### ES5 version
+
+```
+function getUserInfo(data) {
+  data = data === undefined ? {} : data;
+  var name = data.name === undefined ? 'ananonumys' : data.name;
+  var age = data.age === undefined ? 20 : data.age;
+  var location = data.location === undefined ? 'india' : data.location;
+  console.log(name, age, location);
+  // print user data
+}
+
+getUserInfo({
+  name: 'neel',
+  age: 22,
+  location: 'canada'
+});
+```
+
+#### ES2015 version
+
+```
+function getUserInfo({name = 'ananonumys', age = 20, location = 'india'} = {}) {
+  console.log(name, age, location);
+  // print user data
+}
+
+getUserInfo({
+  name: 'neel',
+  age: 22,
+  location: 'canada'
+});
+```
+
+> In the function signature for `getUserInfo` above, the destructured left-hand side is assigned to an empty object literal on the right-hand side: `{name = 'ananonumys', age = 20, location = 'india'} = {}`. You could have also written the function without the right-hand side assignment. However, if you leave out the right-hand side assignment, the function will look for at least one argument to be supplied when invoked, whereas in its current form, you can simply call `getUserInfo()` without supplying any parameters. The current design is useful if you want to be able to call the function without supplying any parameters, the other can be useful when you want to ensure an object is passed to the function.
+
+### Nested object and array destructuring
+
+```
+var metadata = {
+    title: 'Scratchpad',
+    translations: [
+       {
+        locale: 'de',
+        localization_tags: [],
+        last_edit: '2014-04-14T08:43:37',
+        url: '/de/docs/Tools/Scratchpad',
+        title: 'JavaScript-Umgebung'
+       }
+    ],
+    url: '/en-US/docs/Tools/Scratchpad'
+};
+
+var {title: englishTitle, translations: [{title: localeTitle}]} = metadata;
+
+console.log(englishTitle); // "Scratchpad"
+console.log(localeTitle);  // "JavaScript-Umgebung"
+```
+
+### For of iteration and destructuring
+
+```
+var people = [
+  {
+    name: 'Mike Smith',
+    family: {
+      mother: 'Jane Smith',
+      father: 'Harry Smith',
+      sister: 'Samantha Smith'
+    },
+    age: 35
+  },
+  {
+    name: 'Tom Jones',
+    family: {
+      mother: 'Norah Jones',
+      father: 'Richard Jones',
+      brother: 'Howard Jones'
+    },
+    age: 25
+  }
+];
+
+for (var {name: n, family: {father: f}} of people) {
+  console.log('Name: ' + n + ', Father: ' + f);
+}
+
+// "Name: Mike Smith, Father: Harry Smith"
+// "Name: Tom Jones, Father: Richard Jones"
+```
+
+### Unpacking fields from objects passed as function parameter
+
+```
+function userId({id}) {
+  return id;
+}
+
+function whois({displayName, fullName: {firstName: name}}) {
+  console.log(displayName + ' is ' + name);
+}
+
+var user = { 
+  id: 42, 
+  displayName: 'jdoe',
+  fullName: { 
+      firstName: 'John',
+      lastName: 'Doe'
+  }
+};
+
+console.log('userId: ' + userId(user)); // "userId: 42"
+whois(user); // "jdoe is John"
+```
+This unpacks the `id`, `displayName` and `firstName` from the user object and prints them.
+
+### Computed object property names and destructuring
+
+```
+let key = 'z';
+let {[key]: foo} = {z: 'bar'};
+
+console.log(foo); // "bar"
+```

+title: Object Freeze
+---
+## Object Freeze
+The `Object.freeze()` method freezes an object. A frozen object will *prevent you* from:
+
+* Adding new properties to it
+* Removing existing proprerties from it
+* Changing the enumerability, configurability, or writeability of it's existing properties
+
+### Syntax
+```javascript
+Object.freeze(obj)
+```
+
+### Parameters
+`obj`
+* The object to freeze.
+
+### Returns
+The frozen object.
+
+### Important Note
+Attempting to add, remove, or modify properties of a frozen object will result in a failure. This failure will either be silent or a thrown `TypeError` (if Strict Mode is enabled). Additionally, `Object.freeze()` is a shallow operation. This means that nested object, of a frozen object, are modifiable.
+
+### Example
+```javascript
+// Create your object
+let person = {
+  name: 'Johnny',
+  age: 23,
+  guild: 'Army of Darkness',
+  hobbies: ['music', 'gaming', 'rock climbing']
+}
+
+// Modify your object
+person.name = 'John'
+person.age = 24
+person.hobbies.splice(1,1)
+delete person.guild
+
+// Verify your object has been modified
+console.log(person) // { name: 'John', age: 24, hobbies: ['music', 'rock climbing']
+
+// Freeze your object
+Object.freeze(person)
+
+// Verify that your object can no longer be modified
+person.name = 'Johnny' // fails silently
+person.age = 23 // fails silently
+console.log(person) // { name: 'John', age: 24, hobbies: ['music', 'rock climbing']
+
+// The freeze is "shallow" and nested objects (including arrays) can still be modified
+person.hobbies.push('basketball')
+consol.log(person.hobbies) // ['music', 'rock climbing', 'basketball']
+
+```

+
+`Object.getOwnPropertyNames()` returns an array whose elements are strings corresponding to the enumerable _and non-enumerable_ properties found directly upon object.

+You can use <b>`Object.isFrozen()`</b> to figure out if an object is frozen or not. It returns a <b>`true`</b> or <b>`false`</b> boolean value. 
+
+<b><h4>SYNTAX</h4></b>
+```javascript
+Object.isFrozen(obj)
+```
+<b>For Example:</b>
+
+```javascript
+var foods = {
+    grain : "wheat",
+    dairy  : "milk",
+    vegetable : "carrot",
+    fruit  : "grape"
+};
+
+var frozenFoods = Object.freeze(foods);
+
+var areMyFoodsFrozen = Object.isFrozen(frozenFoods);
+
+\\ returns true
+
+```
+
+Remember, a frozen object <b>cannot</b> have its properties changed. 
+</br></br>
+If you try to use <b>`Object.isFrozen()`</b> on a non-object argument, it will return `true`.

+title: Object Keys
+---
+The `Object.keys()` method returns an array of a given object's own enumerable properties, in the same order as that provided by a `for...in` loop (the difference being that a `for-in` loop enumerates properties in the prototype chain as well).
+
+## Syntax
+
+    Object.keys(obj)
+
+### Parameters
+
+**obj**
+
+The object whose enumerable own properties are to be returned.

+
+## Description
+
+`Object.keys()` returns an array whose elements are strings corresponding to the enumerable properties found directly upon object. The ordering of the properties is the same as that given by looping over the properties of the object manually.
+
+## Examples
+
+    var arr = ['a', 'b', 'c'];

+
+    // array like object

+    // array like object with random key ordering
+    var an_obj = { 100: 'a', 2: 'b', 7: 'c' };
+    console.log(Object.keys(an_obj)); // console: ['2', '7', '100']
+
+    // getFoo is property which isn't enumerable
+    var my_obj = Object.create({}, { getFoo: { value: function() { return this.foo; } } });
+    my_obj.foo = 1;
+
+    console.log(Object.keys(my_obj)); // console: ['foo']
+
+    // Create a constructor function.
+    function Pasta(grain, width, shape) {
+        this.grain = grain;
+        this.width = width;
+        this.shape = shape;
+
+        // Define a method.
+        this.toString = function () {
+            return (this.grain + ", " + this.width + ", " + this.shape);
+        }
+    }
+
+    // Create an object.
+    var spaghetti = new Pasta("wheat", 0.2, "circle");

+`Object.values()` returns an array whose elements are the enumerable property values found on the object. The ordering of the properties is the same as that given by looping over the property values of the object manually. In other words, an object has key:value pairs, and this method returns all the *values* of that object in an array-like object.

+    // array like object with random key ordering
+    var an_obj = { 100: 'a', 2: 'b', 7: 'c' };
+    console.log(Object.values(an_obj)); // ['b', 'c', 'a']

+    my_obj.foo = 'bar';
+    console.log(Object.values(my_obj)); // ['bar']
+
+    // non-object argument will be coerced to an object
+    console.log(Object.values('foo')); // ['f', 'o', 'o']
