This is the first of my series about things that I found on the internet this week.

Coding

• When to useMemo and useCallback. This is oldpiece by Kent but I’ve got it in his weekly newsletter. Reading through examples requires some workbut I’ve got this phrase: Do not bother with optimization unnecessary. To be honest (maybe) I’m lucky but I don’t yet need to use useMemo or useCallback.
• I’ve read two pieces about HTML numeric inputs: Why the GOV.UK Design System team changed the input type for numbers & HTML attributes to improve your users’ two factor authentication experience and I’ve learned about inputmode="numeric".I’ve to try it at work where we use type="tel" for better postal code experience on mobile.
• I learned that you can have CSS Grid inside your buttons too! I’ve made a quick codepen example. Source.

Other

• Interesting piece on how to work from home & about asynchronous communication.
