what is the use of bind method in javascript

Comment

"Variables has local and global scopes. Let's suppose that we have two variables
with the same name. One is globally defined and the other is defined inside a
function closure and we want to get the variable value which is inside the
function closure. In that case we use this bind() method.

code:

var x = 9; // this refers to global "window" object here in the browser

var person = {
  x: 81, // local variable x = 81
  getX: function() {
    return this.x; // "this" = person , so this.x is the same as  person.x
  }
};
//  the next line of code is the most important one (line 17)
var y = person.getX; // It will return 9, because it will call global value of x(var x=9).

var myFunc = y.bind(person); // It will return 81, because it will call local value of x, which is defined in the object called person(x=81).

y(); // return 9 (the global variable);

myFunc();" // return 81 (the loacl variable);

bind method in javascript

Comment

let obj = {
    name: "Abhi",
    age: 28,
    info: function() {
        console.log(`${this.name}  is  ${this.age} year's old`);//template literals used here
    },
};
let obj1 = {
    name: "Vikash",
    age: 28,
};

obj.info.bind(obj1)(); //since bind methods return a new function so 
//we can directly call that function[()] without pollouting global
//space while assigning a varibale to call that function.
//Always try to make global space neat n clean ,
//dont polloute while assigning unnecessary variables.

bind() returns a bound function that, when executed later, will have the correct context ("this") for calling the original function.

Javascript bind()

Comment

The bind() method returns a new function, and when invoked, it has its 'this' set to a specific value.

Syntax: functionName.bind(Object to borrow values from, ...argsN)

let runner = {
    name: 'Runner',
    run: function(speed) {
        console.log(this.name + ' runs at ' + speed + ' mph.');
    }
};

let flyer = {
    name: 'Flyer',
    fly: function(speed) {
        console.log(this.name + ' flies at ' + speed + ' mph.');
    }
};

// Uses values of 'flyer' instead of 'runner', 
// cause of the bind(), vice versa;
let run = runner.run.bind(flyer, 20);
run(); // logs "Flyer runs at 20 mph."

// With love @kouqhar

The bind() method allows an object to borrow a method from another object without making a copy of that method.

This is known as function borrowing in JavaScript.

JavaScript Function bind()

Comment

		const person = {
name: "John Smith",
getNameAndAddress: function()
{
return this.name;
}

}
const personWithoutGet = {
name: "Jerry Smithers"}

 console.log(person.getName.bind(personWithoutGet);
  }

/*you can think of bind() apply()  and call() ALL as "stealing someone else's function to use."*/
/* victimBeingStolenFrom.functionName.call(theThief) */
/*notice the second variable personWithoutGet does not have a getName function*/
