|  | 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 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. |
