Syntax

a == b

Description

The == operator compares two arguments and yields a boolean. If a is equal to b, then a==b yields true. If a is not equal to b, then a==b yields false. It is typically used in an if-statement.

Example

Note

The normal equal sign (=) should only be used for equations. The equal sign (=) makes the left side of an equation equal to the right side. This is different to the equal statement (==) which compares two arguments and yields a boolean.
