Could you cite an actual specific example? I have a difficult time believing what you are asserting that it provided absolutely no value at any point - it just sounds like a baseless ad hominem attack.

I find that it's fantastic for typescript and JavaScript allowing me to flesh out the completion of basic data object containers class definitions etc. extremely quickly.

If I don't remember the exact parameters that you have to pass into a certain NPM packages methods it will usually auto prompt me and help me complete it without me having to context switch to a browser and look it up.
