true

The true constant represents the Boolean output true. Its opposite is false.

true
Code language: JavaScript (javascript)

Type true into a Notion formula property, and that property will output a checked checkbox, representing the value true.

A Boolean value has only two states, which can be thought of as:

• True or False
• 1 or 0
• On or Off

A Boolean simply represents the two truth values of logic.

Notion represents Boolean values with checked (true) and unchecked (false) checkboxes.

Example Formulas

This formula will simply output true in a Notion formula property, displaying as a checked checkbox:

true
Code language: JavaScript (javascript)

Here’s a slightly more complex example formula that uses Notion’s if function:

true ? "😀" : "😭"
Code language: JavaScript (javascript)

This is an if() statement written in shorthand – it could also be written as if(true,"😀","😭"). It will simply output 😀 if the condition is true. The condition is the first part of the if() statement, or what is left of the ? in the shorthand formula.

Since the Boolean true outputs true naturally, the result will be 😀. See the Happy property in the example database below for proof.

Example Database

true and false are case-sensitive. Typing True or False will result in a syntax error.

Here you can see how Notion displays true and false Boolean values. You can also see the output of our Happy formula, which is shown above.
