how can I pass multiple parameters in javascript function

Question

function ceshi(test,lyj,param1,parm2){
    console.log(arguments)
}
var params = [2,3];
ceshi(eval('2,3'));

if params is not uncertain, how can I pass params through a method.I want to realize below result.

the function has fixed params,but I have more than one function like

ceshi(1,2,123)
ceshi(1,3123)
ceshi('xxx','ssssss','12313',12)

Answer 1

You can use spread operator in ECMAScript 6 like this:

function ceshi(...params) {
  console.log(params[0]);
  console.log(params[1]);
  console.log(params[2]);
}

Or use the "arguments" variable within a function like this:

function ceshi() {
  console.log(arguments[0]);
  console.log(arguments[1]);
  console.log(arguments[2]);
}

To understand further deeper, I will highly recommend you to read this material.

Answer 2

To call a function, by passing arguments from an array

1. Either use spread operator ceshi(...params)
2. Use apply function to invoke it ceshi.apply(<Context>, params)
