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);


Output:

Vaibhav
11th A
24
