isMatchWith source npm

_.isMatchWith(object, source, [customizer])

This method is like _.isMatch except that it accepts customizer which is invoked to compare values. If customizer returns undefined comparisons are handled by the method instead. The customizer is invoked with three arguments: (objValue, srcValue, index|key, object, source).

Arguments

  1. object (Object)

    The object to inspect.

  2. source (Object)

    The object of property values to match.

  3. [customizer] (Function)

    The function to customize comparisons.

Returns (boolean)

Returns true if object is a match, else false.

Example

function isGreeting(value) {
  return /^h(?:i|ello)$/.test(value);
}

function customizer(objValue, srcValue) {
  if (isGreeting(objValue) && isGreeting(srcValue)) {
    return true;
  }
}

var object = { 'greeting': 'hello' };
var source = { 'greeting': 'hi' };

_.isMatchWith(object, source, customizer);
// => true
