## Usage
38+
39+
```javascript
40+
var everyOwnBy = require( '@stdlib/object/every-own-by' );
41+
```
42+
43+
#### everyOwnBy( object, predicate\[, thisArg ] )
44+
45+
Tests whether all `own` properties of an object pass a test implemented by a `predicate` function.
46+
47+
```javascript
48+
function isPositive( value ) {
49+
return ( value > 0 );
50+
}
51+
52+
var obj = {
53+
'a': 1,
54+
'b': 2,
55+
'c': 3,
56+
'd': 4
57+
};
58+
59+
var bool = everyOwnBy( obj, isPositive );
60+
// returns true
61+
```
62+
63+
If a `predicate` function returns a non-truthy value, the function **immediately** returns `false`.
64+
65+
```javascript
66+
function isPositive( value ) {
67+
return ( value > 0 );
68+
}
69+
70+
var obj = {
71+
'a': 1,
72+
'b': -2,
73+
'c': 3,
74+
'd': 4
75+
};
76+
77+
var bool = everyOwnBy( obj, isPositive );
78+
// returns false
79+
```
80+
81+
The invoked `function` is provided three arguments:
82+
83+
- **value**: property value.
84+
- **key**: property key.
85+
- **obj**: input object.
86+
87+
To set the function execution context, provide a `thisArg`.
88+
89+
```javascript
90+
function sum( value ) {
91+
if ( value < 0 ) {
92+
return false;
93+
}
94+
this.sum += value;
95+
this.count += 1;
96+
return true;
97+
}
98+
99+
var obj = {
100+
'a': 1,
101+
'b': 2,
102+
'c': 3
103+
};
104+
105+
var context = {
106+
'sum': 0,
107+
'count': 0
108+
};
109+
110+
var bool = everyOwnBy( obj, sum, context );
111+
// returns true
112+
113+
var mean = context.sum / context.count;
114+
// returns 2
115+
```

## Notes
126+
127+
- If the 1st argument is not an [`object`][mdn-object] or the second argument is not a fuction , the
128+
function throws a Type Error.
129+
130+
- If provided an empty object, the function returns `true`.
131+
132+
```javascript
133+
function untrue() {
134+
return false;
135+
}
136+
var bool = everyOwnBy( {}, untrue );
137+
// returns true

{{alias}}( object, predicate[, thisArg ] )
3+
Tests whether every own property of an object pass a test implemented by a
4+
predicate function.
5+
6+
The predicate function is provided three arguments:
7+
8+
- value: property value.
9+
- index: property key.
10+
- object: the input object.
11+
12+
The function immediately returns upon encountering a non-truthy return
13+
value.
14+
15+
If provided an empty object, the function returns `true`.
16+
17+
Parameters
18+
----------
19+
object: Object
20+
Input object.
21+
22+
predicate: Function
23+
Test 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 truthy
32+
value for all elements; otherwise, the function returns `false`.
33+
34+
Examples
35+
--------
36+
> function positive( v ) { return ( v > 0 ); };
37+
> var obj = { 'a': 1, 'b': 2, 'c': 3 };
38+
> var bool = {{alias}}( obj, positive )
39+
true
