Call

Share This Post

There are some different ways to run a function rather than the traditional way. One of them is by using “call”. The advantages of “call” is it changes the scope of “this”. Here is an example…

let animal = {
    animalName: ‘Bongo’,
    getName: function(){ 
       return this.animalName;
    }
};
let newAnimal = { animalName: ‘George’ }; console.log(animal.getName.call(newAnimal));

The output would be “George”. By using “call” and passing new data, we are shifting the “this” reference to the newAnimal variable. This is handy as it gives us flexibility to use a function in multiple contexts.

Happy Coding!
