 # Iterate with JavaScript For Loops

+### Hint 1
+```javascript
+for(var i = 0; i < 5; i++) {  // There are 3 parts here
+```
 
+There are three parts to for loop. They are separated by semicolons.
+
+1. The initialization: `var i = 0;` - This code runs only once at the start of the loop. It's usually used to declare the counter variable (with `var`) and initialize the counter (in this case it is set to 0).
+
+2. The condition: `i < 5;` - The loop will run as long as this is `true`. That means that as soon as `i` is equal to 5, the loop will stop looping. Note that the inside of the loop will never see `i` as 5 because it will stop before then. If this condition is initially `false`, the loop will never execute.
+
+3. The increment: `i++` - This code is run at the end of each loop. It's usually a simple increment (`++` operator), but can really be any expression. It is used to move the counter (`i`) forward (or backwards, or whatever).

+### Hint 1
+So be careful while using the `if`, `else if` and `else` statements and always remember that these are executed from top to bottom. Keep this in mind placing your statements accordingly so that you get the desired output.

 # Quoting Strings with Single Quotes

+---
+## Problem Explanation
+String values in JavaScript may be written with single or double quotes, so long as you start and end with the same type of quote. Unlike some languages, single and double quotes are functionally identical in JavaScript.

+```
+"This string has \"double quotes\" in it"
+```
 
+The value in using one or the other has to do with the need to escape quotes of the same type. If you have a string with many double quotes, this can be difficult to read and write. Instead, use single quotes:
+
+```
+'This string has "double quotes" in it. And "probably" lots of them.'
+```
