Passing an array as a function parameter in JavaScript

Question

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_         


        

Answer 1

you can use spread operator in a more basic form

[].concat(...array)

in the case of functions that return arrays but are expected to pass as arguments

Example:

function expectArguments(...args){
  return [].concat(...args);
}

JSON.stringify(expectArguments(1,2,3)) === JSON.stringify(expectArguments([1,2,3]))
