The Lodash _.bind() method is used to create a function that will invoke the given function with the this binding of thisArg and it is used to bind a function to an object. When the function is called, the value of this will be the object. The _.bind.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for partially applied arguments.
Syntax:
_.bind(func, thisArg, partials)
Parameter: This method accepts three parameters as mentioned above and described below:
- func: This parameter holds the function that will bind.
- thisArg: This parameter holds the object elements.
- partials: This parameter needs to add some symbols between the elements.
Return value: This method returns a new bound function.
The below example illustrates the Lodash _.bind() method:
Example 1:
Javascript
// Acquiring lodash variable const _ = require( 'lodash' ); // Function var fun = function (Geeks) { return 'Company Name : ' + this .Company + '\nAddress : ' + this .Address + '\nContact : ' + this .Contact }; // Use of bind() function var func = _.bind(fun, { Company: 'neveropen' , Address: 'Noida' , Contact: '+91 9876543210' }); console.log(func()); |
Output:
Company Name : neveropen Address : Noida Contact : +91 9876543210
Example 2:
Javascript
// Lodash variable const _ = require( 'lodash' ); var obj = { Name: "neveropen" , Address: "Noida" }; var fun = function (Geeks) { return 'Welcome to ' + this .Name + '\nAddress: ' + this .Address }; var func = _.bind(fun, obj); console.log(func()); |
Output:
Welcome to neveropen Address: Noida
