"Throwing" reflections

• Buggy code became easier to reason about

• Find bad ("unrecoverable") errors at the point that they occur

• Better than nothing, but often good mostly as a memo to fix the error case

  • Or if you have no idea how the code could have gone wrong
  • Useful for "post-" and "pre-conditions"

• May have to wrap in //try///catch at some point -- where?

  • Have to remember to wrap in //try///catch

// try { throw new Error('hello') // } catch (e) { // console.log(e) // }
