Updated to clarify 'false' is returned if "none" of the elements met the condition, instead of "any". Also edited the last sentence a little.

title: Some Function

## 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 none 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 the `some()` function to an iterable object it is necessary that the object is an Array.
