Question

What are the different ways in which you can define a JavaScript variable?

Answer 1

There are 3 ways:

1. Var – The JavaScript variable statement helps to declare a variable. Alternatively, it can also be used to initialize the value of that specific variable. 
2. Const: The const functions are used so as to not allow the modification of the object on which it is called. So, when a function is said to be const, the function can be called on any object type.
3. Let: Let is used as a signal that shows that a variable can be reassigned, like a counter in a loop or that value swap within an algorithm.
