Exactly. I have recently had a few cases where I've rewritten bloated overly-complex js into 10% to 20% of the LOC. The big benefit is the drastic complexity reduction. Suddenly the junior developers look like superstars because they can understand it and their productivity soars. I'm continually surprised at how otherwise smart engineers end up writing boated spaghetti that is 'correct' at the micro level but ridiculous at the macro level. A few poorly chosen abstractions can increase the cost of development by 10x easily.
