Passing an array as a function parameter in JavaScript

I'd like to call a function using an 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 ) {
  // ...
}

Is there a better way of passing the contents of x into call_me()?

Why don't you pass the entire array and process it as needed inside the function?

var x = [ 'p0', 'p1', 'p2' ]; 
call_me(x);

function call_me(params) {
  for (i=0; i<params.length; i++) {
    alert(params[i])
  }
}

Assuming that call_me is a global function, so you don't expect this to be set.

var x = ['p0', 'p1', 'p2'];
call_me.apply(null, x);
