How to Pass an Array as Arguments to a JavaScript Function?

Passing Array Arguments to JavaScript Functions

In JavaScript, arrays can provide input to functions as parameters. However, extracting individual elements for function calls can be cumbersome. Consider the following example:

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

Is there a more efficient approach to pass the contents of x into call_me()?

There are several ways to pass an array as function parameters:

• apply() Method:

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

This method takes the array's contents as individual arguments, providing a cleaner syntax compared to manual element extraction.

• Spread Operator (ES6 ):

call_me(...args);

If the environment supports ECMAScript 6, the spread operator provides a concise alternative to the apply() method:

call_me(args);

The spread operator expands the array into individual arguments, making it more convenient for passing multiple values into a function.
