The JavaScript Apply() Function

Comment

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

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

 console.log(person.getNameAndAddress.apply(personWithoutGet, ['Berlin','Germany']));
  }

/*you can think of apply() as "stealing someone else's function to use."*/
/* victimBeingStolenFrom.functionName.call(theThief,[any additional parameters as elements in an array]) */
/*notice the second variable personWithoutGet does not have a getName function*/
 /*the difference between call and apply is that call accepts additional parameters separately while apply (this A) accepts the parameters as an array*/

The apply() method accepts arguments in an array:

var arr = [6, 89, 3, 45];
var maximus = Math.max.apply(null, arr); // returns 89

Javascript apply()

Comment

The apply() method is similar to the call() method except that it takes the arguments of the functions as an array instead of the individual arguments.

Syntax: functionName.apply(Object to borrow values from, [...argsN])

const person = {
  firstName: "John",
  lastName: "Doe"
}

function greet(greeting, message) {
    return `${greeting} ${this.firstName} ${this.lastName}. ${message}`;
}

let result = greet.apply(person, ["Hello", "How are you?"])
console.log(result) // logs "Hello John Doe. How are you?"

// With love @kouqhar

The apply() method allows an object to borrow the method of another object without duplicating the code.

If you use the call() method, you need to pass the arguments of the greet() function separately as follows;let result = greet.call(person, "Hello", "How are you?")
