Call() Method in JavaScript

“ lets us understand the use of call( ) in javascript ”

Call( ) method is used for using methods of one object in other object

const obj1={
        f_name : "xyz",
        l_name : "zyx",
        print  : function(){
        console.log(`first Name : ${ this.f_name } , 
                     last Name  : ${this.l_name} `)
                           }
}
obj1.print();
const obj2={
        f_name : "efg",
        l_name : "gfe",
       }

Now how to use print() method of obj1 in obj2 ?

To use print method of obj1 in obj2 we use call() method

const obj2={
        f_name : "efg",
        l_name : "gfe",
       }
obj1.print.call(obj2) 
 /* by using call() we used method of obj1 in obj2*/

now lets see how to pass arguments in call() method

Syntax : obj.method().(obj,arguments)

const obj1={
f_name : "xyz",
        l_name : "zyx",
        print  : function(title){
        console.log(` ${title} . first Name : ${ this.f_name } , 
                     last Name  : ${this.l_name} `)
                           }
}
obj1.print("Mr"); // this method of passing arguments is know 
const obj2={
        f_name : "efg",
        l_name : "gfe",
       }
obj1.print.call(obj2,"Mr")
/* this is how arguments are passed in call() method */
