FunctionName.call(Object/function whose values you want to use as arguments for the 'this' in a function, arg1, arg2, ...argN), if your function needs to receive arguments, pass the arguments in place of ...arg.

const car = {
  name: 'car',
  start() {
    console.log('Start the ' + this.name);
  },
  speedUp() {
    console.log('Speed up the ' + this.name);
  },
  stop() {
    console.log('Stop the ' + this.name);
  },
};

const aircraft = {
  name: 'aircraft',
  fly() {
    console.log('Fly');
  },
};

car.start.call(aircraft);
car.speedUp.call(aircraft);
aircraft.fly();

/*
	// Outputs
    	Start the aircraft
        Speed up the aircraft
        Fly
*/

// With love @kouqhar

By default, the this inside the function is set to the global object i.e. window in the web browsers and global in Nodejs.

The JavaScript call() Method

Comment

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

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

 console.log(person.getNameAndAddress.call(personWithoutGet, 'Berlin','Germany'));
/*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*/
