What don't you like about try/catch? I find the opposite true, the .then/.catch is more confusing.

  try/catch introduces new block scopes and interrupt control flow. I find this example very readable, but expanding it into try/catches would make it rather long winded and harder to see the pattern at work as you extend the sequence: get() .then(handleResult) .catch(useFallbackResult) .then(updateState) I prefer concision and functional expressiveness because it reduces the surface area for writing buggy code. Much like how using map instead writing a for loop can eliminate out of range index bugs, chaining promises brings useful guarantees about how the code I do write can be interpreted.
