Excepted

excepted.mp4

How to switch between Actual & Excepted?

Just open backend folder from VSCode

Interesting facts

• On my daily using (6-8 folders with macOS Native tabs) using Workspaces feature reduces my memory usage up-to 4-5 times (from 14GB to ~3GB) while increasing CPU usage by 3-x (so coolers forgets about silent)
• On workspaces (6-8 folders) using launch tasks uses CPU very aggressively so CPU coolers keeps at max almost always
• On workspaces easier to work and opening terminals, so it increases productivity up-to 20% and it's huge if calculate per year

Closing as a duplicate of microsoft/TypeScript#50595

[dalisoft]

@mjbvz These are different case. THIS for workspace, the linked is for invalid adding src path

[dalisoft]

@mjbvz The issue you linked and marked this as duplicate of that issue is now almost solved by changing tsconfig/jsconfig but this issue is not solved. Please re-open this issue
