I forgot where I saw this a while back but I wanted to documented here for anyone who might find it helpful (future me).
So when you have to check a value against other values rather than doing a bunch of if else statements
const value_to_check: string = "purple";
if ("green" === value_to_check) {
// do the thing
} else if ("red" === value_to_check) {
// do the thing
} else if ("blue" === value_to_check) {
// do the thing
}
or doing a switch statement
const value_to_check: string = "purple";
switch (value_to_check) {
case "red":
// do the thing
break;
case "green":
// do the thing
break;
case "blue":
// do the thing
break;
default:
// do the thing
}
It is best to do the following. It is also really nice on the eyes.
const value_to_check: string = "purple";
if (["green", "blue", "red"].includes(value_to_check)) {
// do the thing
}
