Native Try/Catch vs. Custom tryCatch Function in a Loop (v13)

Revision 13 of this benchmark created on

Description

Investigating a means of replacing the try catch block with a custom solution for performance intensive operations in a loop.

Setup

function tryCatch (tryFn, catchFn) {
      try {
        tryFn()
      } catch (e) {
        catchFn(e)
      }
    }
    
    function tryError (fn) {
      try {
        fn()
      } catch (e) {
        return e
      }
    }
    
    function cachedTry () {
      if (Math.random() > 0.9) {
        throw new Error
      }
    }
    
    function cachedCatch (e) {
      console.log(e)
    }
