Passing an array as a function parameter in Javascript

Question

Below is my code to call a function using array as parameters:

const x = ['p0', 'p1', 'p2'];

call_me(x[0], x[1], x[2]); // I don't like it

function call_me (param0, param1, param2 ) {

  // ...

}

Can anyone tell me what’s the best way to pass the contents of x into call_me()?

Answer 1

Check the code below with uses Function.prototype.apply(): 

const args = ['p0', 'p1', 'p2'];

call_me.apply(this, args);

You can use spread argument, if you have ECMAScript 6: 

call_me(...args);
