# true value

The `true` value means true. It can be used in conditionals with `if` and `elseif` to test them for truth, and also with the help of `true` you can determine the presence of an element or property.

## Syntax

`true;`

## Example

Let's check if the array contains the letter `'a'`:

`let arr = ['a', 'b', 'c', 'd']; console.log(arr.includes('a'));`

The code execution result:

`true`

## Example

Let's check if a value of the variable is equal to `1`:

`let num = 1; console.log(num === 1);`

The code execution result:

`true`

## Example

Let's check the result of the condition:

`let test = true; if(test === true) { console.log('+++'); } else { console.log('---'); }`

The code execution result:

`'---'`
