create a multi loop in javascript

To create a multi loop or nested loop in JavaScript, you can use a combination of for loops or while loops. Here's an example of a nested for loop:

index.tsx
for (let i = 0; i < 5; i++) {
  for (let j = 0; j < 3; j++) {
    console.log(`i is ${i} and j is ${j}`);
  }
}

6 lines

In this example, the outer loop runs five times and the inner loop runs three times for each iteration of the outer loop. The console prints out the value of i and j for each iteration of the loop.

You can also nest other types of loops, like while loops, to create complex iteration patterns. It's important to keep in mind the complexity of your loops, as too many nested loops can lead to performance issues.
