Lodash - isMatchWith method
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));
Save the above program in tester.js. Run the following command to execute this program.
Command
\>node tester.js
Output
true
