💁‍♀️ Cost of updating text in the DOM

⬛️⬛️⬛️⬛️⬛️⬛️ .innerHTML
⬛️⬛️⬛️⬜️⬜️⬜️ .textContent
⬛️⬛️⬜️⬜️⬜️⬜️ .innerText
⬛️⬜️⬜️⬜️⬜️⬜️ .firstChild.data

- Use innerText if you can't assume structure
- Use Text#data to update existing text
A humble benchmark:
esbench.com/bench/590c9cfe…
Clarification for this coming across this:

- The black boxes are a bar graph showing cost (innerHTML is the slowest)

- This is for setting text (writes), not getting text (reads), though it mostly holds true for reads.
💁‍♀️ the above recommendations as a library:

It's inspiring to hear about so many folks using htm to build without tools.

This little library has had more of an impact than I would have thought!

github.com/developit/htm
The next step for htm is to roll over to a custom parser. Right the parser is essentially 1:1 with JSX, which means this is a breaking change.
There's also an option to move to a custom HTML parser. I might run a poll next week to determine what people prefer.

⚖THREAD : POURQUOI LA FAC DE DROIT, C'EST DUR ? ⚖

Ou pourquoi vous avez l’impression de sombrer, et pourquoi abandonner n’est pas forcément une mauvaise idée. (titre non contractuel)

Thanks @Buttarelli_G for this Op-Ed: "Big tech is still violating your #privacy" The "take-it-or-leave it" 'consent' approach shows how strongly network effects lock-in people washingtonpost.com/news/theworldp…
to the incumbent platforms. It's a paradox that the Founding Fathers in the US were fearful of accumulation of power in government but that recent successive governments have let the accumulation of power in Big Tech unchecked supposedly on the belief that competition would keep
actors in check. When #data is increasingly perceived as being an essential facility for a at least number of sectors and its dominant players, it is consequently challenging to build a service which provides the choices that competitive markets are meant to provide when

See details below...
In an arbitration meeting between the two Smile Communications and Eaton Towers (infrastructure provider), it was agreed to reconnect all Smile sites that had been previously switched off to the benefit of all stakeholders concerned & this was done even before the meeting ended.
The parties to the arbitration agreed to sign a temporary addendum to allow re-connection and service restoration pending conclusion of the ongoing negotiations for a new service provisioning agreement.

Cú Chulainn is believed to be an incarnation of the god #Lugh, who is also his father! His mother is the mortal Deichtine, sister of Conchobar mac Nessa, the King of #Ulster who ruled from #NavanFort near #Armagh. #CúChulainn #Irishmyths #Irishlegends #FolkloreThursday
Born Sétanta, Cú Chulainn gained his name as a child, after killing Culann's fierce guard-dog in self-defence & offered to take its place until a replacement could be reared! Used a standing stone or by driving a sliotar down its throat with his hurley! #FolkloreThursday
Cathbad the druid announced one day that anyone who drew arms would have everlasting fame! So Cú Chulainn only 7 years old, asked for arms! But Cathbad grieved because he had not finished his prophecy-the warrior who took arms that day would have a short life! #FolkloreThursday

Sobre el #CódigoRojo -en Jalisco- :

1. ¿Qué es EXACTAMENTE?

2. ¿Quién lo determina y bajo qué criterios?

3. ¿Quién y de qué forma debe anunciarlo a la población?

Sigo con las preguntas ⬇️

@salazargdl @CosaPublica2 @CastelanRob @Pleiotropik @realjosefina @sonia_ssi
4. ¿El protocolo tiene una homologación básica, de caracter nacional o muy a lo Bauman, se inscribe dentro del Ciclo del agua -que estudiamos en la escuela primaria?
5. En este caso: ¿Qué significa el Derecho a la información, por parte de la población?

6. ¿"Debe" ser anunciado OFICIALMENTE a la ciudadanía? o ¿se lo suelta y que corra como pueda, por redes sociales y whatsapp?
