shallowequal
is like lodash'sisEqualWith
but for shallow (strict) equal.
shallowequal(value, other, [customizer], [thisArg])
Performs a shallow equality comparison between two values (i.e. value
and other
) to determine if they are equivalent.
The equality is performed by iterating through keys on the given value
, and returning false
whenever any key has values which are not strictly equal between value
and other
. Otherwise, return true
whenever the values of all keys are strictly equal.
If customizer
(expected to be a function) is provided it is invoked to compare values. If customizer
returns undefined
(i.e. void 0
), then comparisons are handled by the shallowequal
function instead.
The customizer
is bound to thisArg
and invoked with three arguments: (value, other, key)
.
NOTE: Docs are (shamelessly) adapted from lodash's v3.x docs
$ yarn add shallowequal
# npm v5+
$ npm install shallowequal
# before npm v5
$ npm install --save shallowequal
const shallowequal = require('shallowequal');
const object = { 'user': 'fred' };
const other = { 'user': 'fred' };
object == other;
// → false
shallowequal(object, other);
// → true
Code for shallowEqual
originated from https://github.com/gaearon/react-pure-render/ and has since been refactored to have the exact same API as lodash.isEqualWith
(as of v4.17.4
).
