### Variables naming convention:

1.  Variables in JavaScript are **case-sensitive**. Case-sensitive means variables are treated differently depending on whether it is in capitals or lower-case text.

let name="Bob William";
console.log(name);

let NAME ="Jacob Thomas";
console.log(NAME);

We will get two different outputs because the `name` and `NAME` are two different variables.

The syntax of the JavaScript programming language is the set of rules that defines how a JavaScript program will be written and interpreted (by both the runtime system and by human readers).

JavaScript is dynamically typed (also called loosely typed) scripting language. That is, in javascript variables can receive different data types over time. Datatypes are basically typed of data that can be used and manipulated in a program.
