The 5 settings to change in WebStorm right after installation

Map debugging keys to the shortcuts from Chrome, which can't be changed:

• Step Over: F10
• Step Into: F11
• Resume: F8

Editor -> Inlay Hints -> Position: Right, so you don't create a new line for the committer or number of usages of functions/methods

Disable reformatting on paste:
Editor -> General -> Smart Keys -> Reformat on paste: None

Editor -> General -> Tabs -> Mark modified (*)

Editor -> Code Style -> TypeScript: use single quotes

If you work with Markdown:

• Editor -> General -> Soft wraps -> Soft-wrap these files: add .mdx
• (New in WebStorm 2023.1.2) Disable Markdown table reformatting on typing (if you don't want to create large diffs when updating just a few characters in a table that's formatted differently from how WebStorm would like): Uncheck Editor -> General -> Smart Keys -> Markdown -> Reformat table when pasting
