Find the Discord channel in which you would like to send commits and other updates

In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

I've recently ran into a pitfall of [React.memo()
][memo] that seems generally overlooked; skimming over the top results in Google just finds it mentioned in passing in a [React issue][regit], but not in the [FAQ] or API [overview][react-api], and not in the articles that set out to explain React.memo()
(at least the ones I looked at). The issue is specifically that nesting children defeats memoization, unless the children are just plain text. To give a simplified code example:
const Memoized = React.memo(({ children }) => (<div>{children}</div>));
// Won't ever re-render
<Memoized>bar</Memoized>
// Will re-render every time; the memoization does nothing
Memoization is a somewhat fraught topic in the React world, meaning that it's easy to go wrong with it, for example, by [making memo()
do nothing][memo-pitfall] by passing in children to a component. The general advice is to avoid memoization until the profiler tells you to optimize, but not all use cases are general, and even in the general use case you can find tricky nuances.
Discussing this topic requires some groundwork about the technical terms, and I'm placing these in once place so that it's easy to skim and skip over:
- Memoization means caching the output based on the input; in the case of functions, it means caching the return value based on the arguments.
- Values and references are unfortunately overloaded terms that can refer to the low-level implementation details of assignments in a language like C++, for example, or to memory
The package that linked you here is now pure ESM. It cannot be require()
'd from CommonJS.
This means you have the following choices:
- Use ESM yourself. (preferred)
Useimport foo from 'foo'
instead ofconst foo = require('foo')
to import the package. You also need to put"type": "module"
in your package.json and more. Follow the below guide. - If the package is used in an async context, you could use
await import(…)
from CommonJS instead ofrequire(…)
. - Stay on the existing version of the package until you can move to ESM.
