The main difference between int and byte in Java is the size of their respective data types. An int is a 32-bit integer and a byte is an 8-bit integer.

How to generate random strings in JavaScript?
You can generate random strings in JavaScript by using the Math.random() method to generate random numbers between 0 and 1, then combining those numbers with a character set to form the random strings. Here’s an example of how you might do it:
// Generate random strings in JavaScript
// Choose characters to include in our random strings
const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
// Get the length of the characters string
const charLength = characters.length;
// Initialize an empty string for our random string
let randomStr = '';
// Set the length of our random string
const length = 10;
// Loop through to generate random numbers between 0 and 1
for (let i = 0; i < length; i++) {
// Generate a random number
let randomNumber = Math.random();
// Find the relevant index in the characters string
let index = Math.floor(randomNumber * charLength);
// Append the character at the index to our random string
randomStr += characters[index];
}
// Log the random string to the console
console.log(randomStr);
