Comparison OperatorsComparison Operators

We discussed three comparison operators in previous chapters. However, there are additional operators in this category that we should be familiar with. Below is a list of all the comparison operators:

OperatorLogic
==Equal to
!=Not Equal to
<Less Than
<=Less Than or Equal to
>Greater Than
>=Greater Than or Equal to

Not Equal To (!=)

This operator is used to check if two values are not equal to each other. For example:

go

index.go

Less Than or Equal To (<=)

This operator is used to check if the value on the left is less than or equal to the value on the right:

go

index.go

Greater Than or Equal To (>=)

This operator is used to check if the value on the left is greater than or equal to the value on the right:

go

index.go
