Lodash - isMatchWith method


Advertisements

Syntax

_.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 five arguments: (objValue, srcValue, index|key, object, source).

Arguments

  • object (Object) − The object to inspect.

  • source (Object) − The object of property values to match.

  • [customizer] (Function) − The function to customize comparisons.

Output

  • (boolean) − Returns true if object is a match, else false.

Example

var _ = require('lodash');

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' };
 
console.log(_.isMatchWith(object, source, customizer));
