isEnumerableProperty

Test if an object's own property is enumerable.

Usage

var isEnumerableProperty = require( '@stdlib/assert/is-enumerable-property' );

isEnumerableProperty( value, property )

Returns a boolean indicating if a value has an enumerable property.

var value = {
    'beep': 'boop'
};

var bool = isEnumerableProperty( value, 'beep' );
// returns true

bool = isEnumerableProperty( value, 'constructor' );
// returns false

Notes

In contrast to the native Object.prototype.propertyIsEnumerable, this function does not throw when provided null or undefined. Instead, the function returns false.
```
var bool = isEnumerableProperty( null, 'a' );
// returns false

bool = isEnumerableProperty( void 0, 'a' );
// returns false
```

Value arguments other than null or undefined are coerced to objects.

var bool = isEnumerableProperty( 'beep', '1' );
// returns true

Property arguments are coerced to strings.

var value = {
    'null': false
};
var bool = isEnumerableProperty( value, null );
// returns true

value = {
    '[object Object]': false
};
bool = isEnumerableProperty( value, {} );
// returns true

Examples

var isEnumerableProperty = require( '@stdlib/assert/is-enumerable-property' );

var bool = isEnumerableProperty( { 'a': 'b' }, 'a' );
// returns true

bool = isEnumerableProperty( [ 'a' ], 0 );
// returns true

bool = isEnumerableProperty( [ 'a' ], 'length' );
// returns false

bool = isEnumerableProperty( {}, 'toString' );
// returns false

bool = isEnumerableProperty( {}, 'hasOwnProperty' );
// returns false

bool = isEnumerableProperty( null, 'a' );
// returns false

bool = isEnumerableProperty( void 0, 'a' );
// returns false

bool = isEnumerableProperty( { 'null': false }, null );
// returns true

bool = isEnumerableProperty( { '[object Object]': false }, {} );
// returns true
