Ask HN: Which line of code you have written will be executed the most?

At a fortune 100 company I consulted at, developers were rewarded for writing efficient code that was frequently reused. This was literally micro-transaction recognition and rewards a decade prior to anything resembling today's micro-transaction cloud billing.

I wrote the billing/logging system and I am certain the main "method call logger" is by far the most frequently executed code I have ever written. It was called by any method that the author wanted to be compensated for. Alas, I was not allowed to include the call to this method in the compensation pool :-(

Probably some code I wrote to see how long a for loop would take in js looping a billion times. Not too exiting either

I wrote the backend for a large saas that is in the business of pushing notifications to ios, Android, and browsers.

It's not as cool as being a frequent call at the OS level, but pretty good for an ex web developer.

I think it's very likely still in use, in some part, and surely into the billions of deliveries, so who knows how many executions of some inner loops or whatever.

if err != nil {

Technically: it's things inside of rendering or sim loops.

Philosophically: print debugging.
