JavaScript Apply() Function
The apply() method is used to write methods, which can be used on different objects. It is different from the function call() because it takes arguments as an array.
Syntax:
apply()
Return Value: It returns the method values of a given function.
Example 1: This example illustrates the apply() function without arguments.
Javascript
let student = { details: function () { return this .name + this .class; } } let stud1 = { name: "Dinesh" , class: "11th" , } let stud2 = { name: "Vaibhav" , class: "11th" , } let x = student.details.apply(stud2); console.log(x); |
Output:
Vaibhav 11th
Example 2: This example illustrates the apply() function with arguments.
Javascript
let student = { details: function (section, rollnum) { return this .name + this .class + " " + section + rollnum; } } let stud1 = { name: "Dinesh" , class: "11th" , } let stud2 = { name: "Vaibhav" , class: "11th" , } let x = student.details.apply(stud2, [ "A" , "24" ]); console.log(x); |
