TypeScript while

TypeScript is a statically typed superset of JavaScript that adds optional static typing, classes, interfaces, and more to JavaScript. While loops are commonly used in programming to execute a piece of code repeatedly as long as a condition is met.

In TypeScript, the syntax of the while loop is similar to that of JavaScript. Let's take a look at an example:

let count: number = 0;
while (count < 10) {
  console.log(count);
  count++;
}

In this example, we declare a variable count and initialize it to 0. We then create a while loop with the condition count < 10, which means that the loop will continue to execute as long as count is less than 10.

Inside the loop, we log the current value of count to the console using console.log(). We then increment the value of count by 1 using the ++ operator.

The loop will continue to execute until the value of count is no longer less than 10. At that point, the loop will terminate and the program will move on to the next piece of code.

While loops can be useful in many situations, but it's important to be careful not to create an infinite loop. An infinite loop is a loop that never terminates, causing the program to get stuck in an endless loop.

Here is an example of an infinite loop:

let i: number = 0;
while (i < 10) {
  console.log(i);
}

In this example, we create a while loop with the condition i < 10. However, we never increment the value of i, which means that the loop will never terminate. This will cause the program to get stuck in an infinite loop, which can lead to serious problems.

To avoid creating infinite loops, always make sure that your loop has a clear condition for termination, and that the condition will eventually be met by the loop.
