{{alias}}( collection, predicate[, thisArg ] ) Tests whether at least one element in a collection passes a test implemented by a predicate function. The predicate function is provided three arguments: - value: collection value. - index: collection index. - collection: the input collection. The function immediately returns upon encountering a truthy return value. If provided an empty collection, the function returns `false`. Parameters ---------- collection: Array|TypedArray|Object Input collection over which to iterate. If provided an object, the object must be array-like (excluding strings and functions). predicate: Function The test function. thisArg: any (optional) Execution context. Returns ------- bool: boolean The function returns `true` if the predicate function returns `true` for any element; otherwise, the function returns `false`. Examples -------- > function negative( v ) { return ( v < 0 ); }; > var arr = [ 1, 2, 3, 4, -1 ]; > var bool = {{alias}}( arr, negative ) true See Also --------
