how does the break keyword actually work in JavaScript

why does the code still disregard the rest of the number after 5? I thought it was supposed to skip only number five then start with the rest of the number.

for (i = 0; i <= 10; i++) {
if (i == 5) {
    break; 
}
document.write(i + "<br />");
}

break will quit the loop (similar to return for functions), but continue will skip the rest of the code of that iteration and go to the next iteration:

Example - log all the numbers from 1 to 6 to the console, but do not log 3, and stop logging altogether at 5 (do not log 4 or any other numbers):

for (let i = 1; i < 7; i++) {
  if (i == 3) continue;
  else if (i == 5) break;
  else console.log(i);
}

Use continue to skip as break just breaks out of the loop.

break will break out of the for loop altogether, but continue will skip the rest of that iteration and move onto the next.
