while vs do while javascript

// while vs do...while loops

/* while loops: check condition first. If true, execute code. */
let i = 0; 
while (i < 5) {
  console.log(i); // 0 1 2 3 4
   i += 1;
}

/* do-while loops: execute code at least once even if condition is false. 
Then check condition. If true, continue executing code. */
let j = 6;
do {
  console.log(j); // 6
    j += 1;
} while (j < 5);

difference between for loop and while loop javascript

let i = 0;
//while checking for a state
while (i < 20){
  console.log(`do something while ${i} is less than 20`)
i++;
}
console.log("End of While Loop")
//for iterating a certain number of times
for(j = 0; j < 20; j++){
  console.log(`do something for ${j + 1} time(s)`)
}
console.log("End of For loop")
