+
+## The Some Function
+
+The `some()` function is used for verifying if at least one element of an array meets a given condition. The function returns `true` if the condition is met by one element, and false if any of the elements met the condition
+
+The original syntax of the some function is:
+```javascript
+arr.some(function callback(currentValue, index, array) {
+  // Do some stuff with currentValue (index and array are optionals)
+}, [thisArg]);
+```
+
+### Example (ES6):
+
+```javascript
+const arr = [1, 4, 5, 11];
+if (arr.some(el => el % 2 == 0)) {
+  console.log("There's at least one even number");
+}
+```
+
+`some()` is a method of the `Array` object, so to pass that function to an iterable object it is necessary to be sure that the object is an Array.
