But JavaScript also allows us to increase the length of the array without adding an element. Such an array is called a sparse array. In the tutorial let us learn more about dense and sparse arrays.

An array constructor is a constructor function that allows us to create a new JavaScript Array. Every Javascript array also has a constructor property, which points to the array constructor function.

Arguments Object Objects   Rest Parameters in JavaScript allow us to accept a variable number of arguments as an array. JavaScript introduced this feature in ES6.

Arrow functions Rest Parameters   Arguments object in JavaScript allows us to access the argument values inside the function. In this tutorial, we will show you what is Arguments object and how to access it inside the JavaScript function. We also look at some of its use cases with examples. What is Arguments Object The
