Operators are the heart of every programming language. With operators, you can make comparisons or modifications to and between values. PowerShell offers a big set of operators, and it is important to get comfortable with most of them. You will need them in most of your scripts, and the ones that are not well-known could provide you with additional capabilities to create even more efficient code. You can find information on the operators via Get-Help, as follows:
