@vtrlx I use an IDE most of the time. I see 3 kind of benefits

1. reading assistance
Code navigation, navigable call hierarchy analysis, navigable dependency analysis, finding references, syntax coloration, symbol search (variable, function name, class name in oof languages),quick documentation access, quick source code access

@vtrlx

2. writing assistance
Auto-completion, method suggestion and api discovery these 2 especially when backed by a strong type system), automatic safe refactorings (symbol rename, function extraction, call signature update, capitalisation, and in OO languages class or interface extraction)

3. Trivial interactive debugging especially for tests.
