while Loops

While loop tab tak chalta rehta hai jab tak uski condition true rehti hai — useful hai jab aapko pehle se pata na ho ki kitni baar loop karna hai.

main.ts

let count: number = 0;
while (count < 5) {
  console.log(count);
  count++;
}

Output

break se jaldi bahar niklna

break turant loop se bahar nikal jaata hai, condition kuch bhi ho — bilkul JavaScript ki tarah.

main.ts

let n: number = 0;
while (true) {
  if (n === 3) {
    break;
  }
  console.log(n);
  n++;
}

Output

0
1
2
