list - If variable is equal to value or another value - javascript -


i'm trying write simple pig latin code. want check if first letter of input string vowel, if run code. how can ask if y equal 1 of values. 

function piglatin() {     var y = prompt("enter word:")     if (y.charat(0) = a,e,i,o,u) {         var piglatin = y + "ay";         document.getelementbyid("answer").innerhtml = "answer is: " + piglatin;     } else {         var wordlength = y.length + 1;         var piglatin = y.substring(1, wordlength) + y.charat(0) + "ay";         document.getelementbyid("answer").innerhtml = "answer is: " + piglatin;     } } 

if (y.charat(0) = a,e,i,o,u) {

...is not valid.

try...

if ('aeiou'.includes(y.charat(0))) {

your problems are...

  • strings must quoted, if they're 1 character long.
  • an array must wrapped [ , ] (unless constructed via means such array constructor)
  • you can't use assignment operator (=), nor equivalency operator (== or ===) automatically check presence of item in array. since you're checking against list of single characters, can directly use string.prototype.includes() on it.

if user cancels prompt(), null also, not handling (it crash on condition mentioned).
