Detect Pangram

❓ Detect Pangram

Q. A pangram is a sentence that contains every single letter of the alphabet at least once. For example, the sentence "The quick brown fox jumps over the lazy dog" is a pangram, because it uses the letters A-Z at least once (case is irrelevant).

Given a string, detect whether or not it is a pangram. Return True if it is, False if not. Ignore numbers and punctuation.

✔ Solution

//#my solution
alphabets = 'abcdefghijklmnopqrstuvwxyz'.split("");

const isPangram = (string) => {
    string = string.toLowerCase();
    return alphabets.every(x => string.includes(x));
}

//#other solution
function isPangram(string){
  return 'abcdefghijklmnopqrstuvwxyz'
    .split('')
    .every((x) => string.toLowerCase().includes(x));
}
