### What are Booleans Values

The boolean data type is either `true` or `false`. In programming, we often need to know if an expression (code snippet which evaluates to some value) is `true` or `false` so in that case, we use boolean values. In JavaScript, boolean variables are defined by the `true` and `false` keywords.

let isClear = true;
console.log(isClear);

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.
