    1. Looks like the problem is that debounce defaults to waiting for 0 ms ... which is completely useless!

      It would be (and is) way to easy to omit the 2nd parameter to https://lodash.com/docs/4.17.15#debounce.

      Why is that an optional param with a default value?? It should be required!

      There must be some application where a delay of 0 is useless. https://www.geeksforgeeks.org/lodash-_-debounce-method/ alludes to / implies there may be a use:

      When the wait time is 0 and the leading option is false, then the func call is deferred until to the next tick.

      But I don't know what that use case is. For the use case / application of debouncing user input (where each character of input is delayed by at least 10 ms -- probably > 100 ms -- a delay of 0 seems utterly useless.

    1. Without elegant ways of expressing loops/iterators (like angular does with directives), the primary way to keep JSX readable thus becomes copying and pasting.

      I'm not quite sure I understand this (so until I do, I'm not sure I agree)...

      Why does he think copying and pasting is the only way to make it readable? Like he pointed out, you can extract JSX snippets and use loops within JSX. But maybe he means (his previous point), that people often don't do that. Hmm. 

    1. trusktr herman willems • 2 years ago Haha. Maybe React should focus on a template-string syntax and follow standards (and provide options for pre-compiling in Webpack, etc).

      Well anywho, there's other projects now like hyperHTML, lit-html, etc, plus some really fast ones: https://www.stefankrause.ne...

      React seems a little old now (and the new Hooks API is also resource heavy).

      • Share › −  trusktr Michael Calkins • 2 years ago True, it matters if you're re-rendering the template at 60fps (f.e. for animations, or for games). If you're just changing views one time (f.e. a URL route change), then 100ms won't hurt at all.

    1. You can see that Rollup mapped browser globals called "React" and "ReactDOM" to variables called "React" and "ReactDOM". The latter are what you imported by writing import React and import ReactDOM. (The variable names don't have to be the same as the browser globals, but it's common.)
    1. The only difference is that they’re named with camelCase like onClick, onFocus, onDragEnter instead of the all-lowercase names from HTML (onclick, onfocus, ondragenter).
