[00:00:00]JavaScript variables and data types.

[00:00:02]Hello friends. Today we'll learn variables and data types in JavaScript.

[00:00:07]Variables are used to store data, for example, your name, age, or city. In JavaScript, we mainly use let, const, and var. Example, JavaScript let name John, let age equals 20, let a student equals true. Here, name is a string, age is a number, a student is a boolean value, string stores text, number stores numeric values, and boolean stores true or false.

[00:00:31]Now let's print the values using console.log.

[00:00:34]JavaScript console log name, console log age, console log is student. To see the output, right-click, click inspect, and open the console tab. Congratulations.
