Execute a method depending on user input without if/else

Depending on the user input ("0", "1", "2") I want to execute a method. What is a good way to do it without

if(input == "0")
  methodA();
else if(input == "1")
  methodB();
etc..

I rather want to fill a map or something equal like this:

"0" -> methodA()
"1" -> methodB()
"2" -> methodC()

find user input in map and execute the corresponding method.

const methods = {
  '0': x => console.log(`method A your input value was ${x}`),
  '1': x => console.log(`method B your input value was ${x}`)  
}

methods['0'](5)
methods['1'](3)

You can have something like this:

 methodA = function () {
    Console.log("A");
 }; 
 methodB = function () {
    Console.log("B");
 };
 methodC = function () {
    Console.log("C");
 };
   
 inpResonse = {
    "0": this.methodA,
    "1": this.methodB,
    "2": this.methodC
 };

and then invoke (inpResponse[input])()
