Answer 1

for (var i = 'a'.charCodeAt(0); i <= 'z'.charCodeAt(0); i++) {
  console.log(String.fromCharCode(i));
}

Answer 2

for(var letter=65;letter<91;letter++)
{
var _char = String.fromCharCode(letter);
console.log(_char);
}

or use from 97 - 123 ascii code for lowercase letters

Answer 3

Here's an improved* version of @Medo Medo's pure JS code:

    var letters=[], letter_first = 'a', letter_last = 'z' // you can also use A and Z
    for (var letter=letter_first.charCodeAt(0);letter<=letter_last.charCodeAt(0);letter++)
      letters.push(String.fromCharCode(letter))
    document.write(letters.join(''))

• Fixed the "var" declaration
• Added direct letter detection
• Collected the result into an array in order to have only one output
• Made the code runnable right here
