In this video, we are going to see the variable declaration of Javascript.

JavaScript variables are placeholder for storing data values.

All JavaScript variables must be defined with unique names.
JavaScript can handle many datatypes, but for now, just we are going to explore numbers and strings.

Strings can be written inside double or single quotes. Numbers are written without quotes.

You declare a JavaScript variable with the var keyword followed by the variable name.
