Multiple if statements (an array)?

Question

How can I get the following function to return multiple color types (not just red, but also orange, yellow, etc.)?

function isRainbowColor(color){
if (color === "red"){
return true;
}else{
return false;
}
}
console.log(isRainbowColor("red"));
//This works but only for one color at a time. Any suggestions?

Answer 1

if (['red','orange','yellow',...].includes(color))

will do the trick ;)
