Multiple strings in one variable js

Question

So i was making some console stuff for my things and i wanted to make some kind of"detection" of command, like if what i input into the thing is command then make it change color of text to white

it did work if i use variable like this

var commands = ['command1'];

or

var commands = 'command1';

but i did not with variable used like in code down there

code:

var commands = ['command1', 'commands2']

window.setInterval(function() {
    if (input.innerHTML.toLowerCase() == !commands) {
        console.log("test")
    }
}, 32);

What are you trying to do with your code at the bottom? Right now, you are checking if the string in the innerHTML is false since ! an array is always false. — Ryan Schaefer

You can check using indexOf. indexOf() returns -1 when the supplied value isn't present

var commands = ['command1', 'commands2']
commands.indexOf(input.innerHTML.toLowerCase()) > -1

var input = document.getElementById("cmd");
var output = document.getElementById("demo"); 

var commands = ['command1', 'commands2'];

input.addEventListener("input", function() {
    var result = null;

    // indexOf() returns -1 when the supplied value isn't present
    if(commands.indexOf(cmd.value.toLowerCase()) > -1){
      // your logic to change color, or do whatever
      result =  "yes";
    } else {
      result = "no";
    }
    output.textContent = result;

});

<input id="cmd">

<p id="demo"></p>
