{{alias}}( x, predicate[, thisArg] )
Tests whether all elements in an array pass a test implemented by a
predicate function.
The predicate function is provided three arguments:
- value: current array element.
- index: current array element index.
- arr: the input array.
If provided an array-like object having an `every` method , the function
defers execution to that method and assumes that the method has the
following signature:
x.every( predicate, thisArg )
If provided an array-like object without an `every` method, the function
performs a linear scan and returns immediately upon encountering a
non-truthy return value.
If provided an empty array, the function returns `true`.
Parameters
----------
x: Array|TypedArray|Object
Input array.
predicate: Function
Predicate function.
thisArg: any (optional)
Execution context.
Returns
-------
bool: boolean
The function returns `true` if the predicate function returns a truthy
value for all elements; otherwise, the function returns `false`.
Examples
--------
> function f( v ) { return ( v > 0 ); };
> var x = [ 1, 2, 3, 4 ];
> var out = {{alias}}( x, f )
true
