What is data types?

JavaScript data types define what kind of values a variable can hold and how those values behave in a program. They determine how data is stored in memory and how operations like comparison, calculation, and conversion work.

Variables:

In JavaScript, variables are named containers used to store data values that your program can manipulate dynamically.

Variables can be declared using var, let, or const.
JavaScript is dynamically typed, so types are decided at runtime.
