Javascript :: for loop vs while loop

ForLoopVsWhileLoop1.js

// loop through string

let letters = 'abcdefg';

// initial: let i=0
// conditional: i<letters.length
// final: i++
for (let i=0; i < letters.length; i++) {
    let currentLetter = letters[i];
    console.log(currentLetter);
}


// "while" loops are interchangeable but you have to remember to put the eventual false condition to avoid looping indefinitely

// init is outside the while loop
let j = 0
while (j < letters.length) {
    let currentLetter = letters[j];
    console.log(currentLetter);
    j++;
}
