PKSpeleo / auto-complete-bug-example

Just repo to reproduce bug in the IntelliJ EDE

This is simple example how IntelliJ Editor and Debugger console context works with code autocomplete (suggestions)

IntelliJ Bug issue

Case 1: not imported module

• Got to file 'hello.js'
• On the line number 3 (after debugger line) start to type: aaa.
• You will see autosuggestion iiHasNotBeenImported

• You can apply and will not see any error or trying to import it from test.js

• The code running will be failed.
• Run debugger, the code will stop on the line 2 (debugger).
• Go to Debugger Console and try to type aaa..
• You will see again iiHasNotBeenImported

Questions:

• Why iiHasNotBeenImported there?
• Why in the editor this suggestion appears if it was not imported?
• Ok, if it was applied - then it must be imported automatically or IntelliJ must highlight the error, but it is looks fine:

• Why this suggestion appear in the Debugger console during run time if it has not been imported? It will not work anyway!

Case 2: Not imported package

• Go to hello.js

• Start typing on the last string aaa.

• You will same as before (from previous example):

• 

• Now install packages:

yarn install --frozen-lockfile

• On the line number 3 (after debugger line) start to type: aaa.
• You will see autosuggestion from installed package:

• Again no errors or automatic import if suggestion was applied:

• Run hello.js in the Debug mode with IntelliJ IDE
• Make sure that code was sopped on the line with 'debugger'
• Got to Debugger console
• Start typing 'aaa.'
• Pay attention on the showed menu with autocompletion suggestions again (america and so on):

Questions:

• Why suggestions are there (america and so on)?
• Why in the editor this suggestion appears if it was not imported?
• Ok, if it was applied - then it must be imported automatically or IntelliJ must highlight the error, but it is looks fine:

• Why this suggestion appear in the Debugger console during run time if it has not been imported? It will not work anyway!
