Test whether a collection contains at least
nelements which are truthy.
var some = require( '@stdlib/utils/some' );Tests whether a collection contains at least n elements which are truthy.
var arr = [ 0, 0, 1, 2, 3 ];
var bool = some( arr, 3 );
// returns trueIf provided an empty collection, the function returns false.
var bool = some( [], 1 );
// returns false- A
collectionmay be either anArray,Typed Array, or an array-likeObject(excludingstringsandfunctions). - The function does not skip
undefinedelements and is thus not optimized for sparse collections.
