30秒学会 JavaScript 片段 – any

Returns true if the provided predicate function returns true for at least one element in a collection, false otherwise.

Use Array.prototype.some() to test if any elements in the collection return true based on fn.
Omit the second argument, fn, to use Boolean as a default.

代码片段

const any = (arr, fn = Boolean) => arr.some(fn);

使用样例

any([0, 1, 2, 0], x => x >= 2); // true
any([0, 0, 1, 0]); // true
