I know how to get the key of a character. for example console.log(String.fromCharCode(70)) would log the letter F

but how do I do the opposite and get the CharCode from a single letter string?

What I tried:

function solution(someword) {
  let oneArray = someword.split("");
  let onekey = String.fromCharCode(oneArray[0])
  console.log(onekey)
}

solution("FROG");

if my word is FROG. it should console log 70 since F is the first letter

Use String.charCodeAt:

function solution(someword) {
    let onekey = someword.charCodeAt(0)
    console.log(onekey) 
}

solution("FROG")
console.log(String.fromCharCode(70))
