generate a random number between 00000 and 99999 in javascript

To generate a random number between 00000 and 99999 in JavaScript, you can use the following code snippet:

index.tsx
let randomNum = Math.floor(Math.random() * 100000); // generates a random integer between 0 and 99999
let formattedNum = String(randomNum).padStart(5, '0'); // pads the number with zeros to ensure it has 5 digits
console.log(formattedNum); // prints the random number in the format 00000 to 99999

The Math.random() function generates a random value between 0 and 1. We then multiply the result by 100000 to get a number between 0 and 99999, and use Math.floor() to round it down to an integer.

To ensure that the number is formatted with leading zeros and has exactly 5 digits, we use the padStart() function. This pads the number with zeros at the start until it has a length of 5.

The final random number is stored in the formattedNum variable and can be used in your program as needed.
