## Usage
38+
39+
```javascript
40+
var noneBy = require( '@stdlib/array/base/none-by' );
41+
```
42+
43+
#### noneBy( x, predicate\[, thisArg] )
44+
45+
Tests whether all elements in an array fail a test implemented by a `predicate` function.
46+
47+
```javascript
48+
function isPositive( value ) {
49+
return ( value > 0 );
50+
}
51+
52+
var x = [ 0, 0, 0, 0 ];
53+
54+
var bool = noneBy( x, isPositive );
55+
// returns true
56+
```
57+
58+
If a `predicate` function returns a truthy value, the function **immediately** returns `false`.
59+
60+
```javascript
61+
function isPositive( value ) {
62+
return ( value > 0 );
63+
}
64+
65+
var x = [ -1, -2, 3, -4 ];
66+
67+
var bool = noneBy( x, isPositive );
68+
// returns false
69+
```
70+
71+
The `predicate` function is provided three arguments:
72+
73+
- **value**: current array element.
74+
- **index**: current array element index.
75+
- **arr**: input array.
76+
77+
To set the `predicate` function execution context, provide a `thisArg`.
78+
79+
```javascript
80+
function predicate( value ) {
81+
this.count += 1;
82+
return ( value < 0 );
83+
}
84+
85+
var x = [ 1, 2, -3, 4 ];
86+
87+
var context = {
88+
'count': 0
89+
};
90+
91+
var bool = noneBy( x, predicate, context );
92+
// returns false
93+
94+
var cnt = context.count;
95+
// returns 3
96+
```

<section class="notes">
105+
106+
## Notes
107+
108+
- The function performs a linear scan and returns immediately upon encountering a truthy return value. Unlike [`Array.prototype.every`][mdn-array-every], when performing a linear scan, the function does **not** skip `undefined` elements.
109+
- If provided an empty array, the function returns `true`.

131+
} );
132+
// returns <Int8Array>
133+
134+
var out = noneBy( x, naryFunction( isPositiveInteger, 1 ) );

{{alias}}( x, predicate[, thisArg] )
3+
Tests whether all elements in an array fail a test implemented by a
4+
predicate function.
5+
6+
The predicate function is provided three arguments:
7+
8+
- value: current array element.
9+
- index: current array element index.
10+
- arr: the input array.
11+
12+
The function performs a linear scan and returns immediately upon
13+
encountering a truthy return value.
14+
15+
If provided an empty array, the function returns `true`.
16+
17+
Parameters
18+
----------
19+
x: Array|TypedArray|Object
20+
Input array.
21+
22+
predicate: Function
23+
Predicate function.
24+
25+
thisArg: any (optional)
26+
Execution context.
27+
28+
Returns
29+
-------
30+
bool: boolean
31+
The function returns `true` if the predicate function returns a falsy
32+
value for all elements; otherwise, the function returns `false`.
33+
34+
Examples
35+
--------
36+
> function f( v ) { return ( v > 0 ); };
37+
> var x = [ 0, 0, 0, 0 ];
38+
> var out = {{alias}}( x, f )
39+
true
