It's not too diffcut in the browser either. Consider how often you're making copies of your data and try to reduce it. For example:

- for loops over map/filter

- maps over objects

- .sort() over .toSorted()

- mutable over immutable data

- inline over callbacks

- function over const = () => {}

Pretty much, as if you wrote in ES3 (instead of ES5/6)

Yes but it's not really fair to expect me to know how to do that. Just because I know how to do it for backend code, where it's often a lot easier to see those copies, doesn't mean I'm just a negligent asshole for not doing it on the frontend. I don't know how, it's a different skillset.

Nobody expects you to know that, but I'm curious to hear how do you know it for backend code but not frontend code. Have any examples?
