Lodash

matches

Util
since 3.0.0

Arguments

  • Object The object of property values to match.

Returns

Function the new spec function.

Creates a function that performs a partial deep comparison between a given object and source, returning true if the given object has equivalent property values, else false.

Note: The created function is equivalent to _.isMatch with source partially applied.

Partial comparisons will match empty array and empty object source values against any array or object value, respectively. See _.isEqual for a list of supported value comparisons.

Note: Multiple values can be checked by combining several matchers using _.overSome

Example of Lodash _.matches

var objects = [
  { 'a': 1, 'b': 2, 'c': 3 },
  { 'a': 4, 'b': 5, 'c': 6 }
];

_.filter(objects, _.matches({ 'a': 4, 'c': 6 }));
// => [{ 'a': 4, 'b': 5, 'c': 6 }]

// Checking for several possible values
_.filter(objects, _.overSome([_.matches({ 'a': 1 }), _.matches({ 'a': 4 })]));
// => [{ 'a': 1, 'b': 2, 'c': 3 }, { 'a': 4, 'b': 5, 'c': 6 }]
