How to Pass Arrays as Function Parameters in JavaScript?

Passing Arrays as Function Parameters in JavaScript

Passing parameters to functions is a fundamental aspect of coding, but how do you pass an entire array as an argument?

const x = ['p0', 'p1', 'p2'];
call_me(x[0], x[1], x[2]); // Lacking elegance

This method of passing parameters can be tedious and error-prone. Thankfully, there are more efficient ways to do it.

Utilizing Function.prototype.apply()

In this approach, we employ the apply() method to pass the array as an argument list.

const args = ['p0', 'p1', 'p2'];
call_me.apply(this, args);

Refer to the MDN documentation for more details on Function.prototype.apply().

Using Spread Arguments

If your environment supports ECMAScript 6, you can use the spread argument syntax for even greater convenience.

call_me(...args);

Both of these methods provide elegant solutions for passing array parameters to functions, making your code more concise and maintainable.
