Difference between let, var, and const variables in JavaScript? Example Tutorial

Hello guys, if you want to understand the difference between var, let, and const in JavaScript then you have come to the right place. Earlier, I have shared the best books and JavaScript courses for beginners and in this article, I will tell you the difference between var, let, and const and when to use them. They are three different ways to declare variables in JavaScript. The var is the classic and old way to declare variables in JavaScript and it can declare both local and global variables, while let and const are new ways to declare variables in Java and they have block scope, I mean they are only visible in the block they are declared. let is used to declare local variables while const is generally used to declare constants, I mean variable whose value doesn't change once initialized.
