Passing an array as a function parameter in JavaScript

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

See MDN docs for Function.prototype.apply().

If the environment supports ECMAScript 6, you can use a spread argument instead:

call_me(...args);

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])
  }
}
