Summary  
This chapter explains how to convert expressions into Boolean values using the Boolean() function to clearly evaluate true or false results.

General domain of usage  
Conditional checks in code

## Simple Applications of `Boolean()` Function
          
We can pass expressions to the Boolean function to check whether it’s `true` or `false`. For example, the following code checks if the number passed to the `Boolean()` function is completely divisible by 3. It returns `true` if the value is completely divisible by 3 and `false` otherwise.

But without `Boolean()` we also get the same result. But Boolean function gives more clarity that Boolean value must return.

### Summary

-   Boolean values are either `true` or `false`.
-   The first letter of Boolean values (true and false) should be written in uppercase.
-   The `Boolean()` method is used to evaluate an expression and returns true or false based on results.

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.
