is-equal-shallow
Does a shallow comparison of two objects, returning false if the keys or values differ.
The purpose of this lib is to do the fastest comparison possible of two objects when the values will predictably be primitives.
- only compares objects.
- only compares the first level of each object
- values must be primitives. If a value is not a primitive, even if the values are the same,
false
is returned.
Install with npm
$ npm i is-equal-shallow --save
Usage
var equals = require('is-equal-shallow');
equals(object_a, object_b);
Examples
equals({a: true, b: true}, {a: true, b: true});
//=> 'true'
equals({a: true, b: false}, {c: false, b: false});
//=> 'false'
equals({a: true, b: false}, {a: false, b: false});
//=> 'false'
Strict comparison for equality:
equals({a: true, b: true}, {a: true, b: 'true'});
//=> 'false'
When values are not primitives, false
is always returned:
equals({ b: {}}, { b: {}});
//=> 'false'
equals({ b: []}, { b: []});
//=> 'false'
