Break And Continue

Break

break is used to forcefully stop loop even if it's condition is met.

let sum = 0; for (let i = 1; i <= 10; i++) { if (sum > 20) { break; } sum += i; } console.log(sum);

Output:

21

line 5 ends the loop though it's condition is fulfilled.

Value of sum is formed by adding i to it (1 + 2 + 3 + 4 + 5 + 6 = 21).

Continue

Continue skips the current iteration of the loop.

for (let i = 1; i <= 6; i++) { if (i == 4) { continue; } console.log(i); }

Output:

1 2 3 5 6

line 3stops the current iteration thus 4 isn't printed.

Unlike breakit doesn't skip the entire loop.
