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.
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);
Example 2: This example illustrates the apply() function with arguments.
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);
