What's the way to terraform lint?

I'm hoping there is something to pick up when I have misspelt variables and comments to save me some time when I'm checking my code and reduce the potential for any errors.

I normally use IntelliJ IDE for Terraform on a MAC but also have VS code set up that I can use.

Is there a plugin for either I could use or even a different tool? The imaging variable might be difficult to lint due as I use underscores to separate words in my variable names so the tool would need to know to treat underscores as white space for linting purposes.
