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.
TLDR; the subtleness of its wrongness destroys my ability to follow my train of thought. I always had to take myself out of my train of thought and evaluate the correctness of the suggestion instead of just writing.
For simple things, intellisense, autocomplete and snippets are far more effective.
For anything more complex, I already know what I want to write.
