That depends on your program. If your function is pure, you can memoize, and then it will be a fast pointer check.

by i_s 11y ago
It is incredibly easy to write a function that creates an input field and keeps track of the state wherever you want, so I don't think that is a valid criticism at all.

Types do have a lot of benefits but they also come with a big cost: some programs are very hard to express in modern type systems. For example, consider a pattern that is becoming more common today in UI programming (even in plain javascrip

You have to implement it yourself. For some apps, you may need to do this anyway for perf reasons, because you don't want to parse the same HTTP response body more than once.

A component being processed via returning false from shouldComponentUpdate is very very different from a component being processed by running the render method and then doing a diff, so that is not a good model.
98.
by i_s 11y ago
No it isn't, I'm talking about avoiding render computation, and then therefore the diffing. If 1 render method gets called that contains 10 elements, and 99 other render methods are not called because of returning false from shoul
99.
by i_s 11y ago
Yeah, but if you chunk the items (groups of 10, lets say) in components, you can return false from shouldComponentUpdate in all but the last component, and therefore be fast.

by i_s 11y ago
Yeah, but this is significantly worse than performance comparisons that have already been done. See here for example: http://elm-lang.org/blog/blazing-fast-html TodoMVC is way more realistic because items are actually

Some of the criticisms the author points out still hold. For example, criticism that React doesn't give a place to plug in to do post-processing on nodes is valid, and is even a point that David Nolen makes in the video you linked to.

Almost any native UI framework (iOS, Android, WPF on windows, etc) has better layout options. Some of them like iOS have options that are not as beginner friendly (AutoLayout), but they are still better overall if you are trying to develop

Imperative coding may be useful to for implementing the API, but that does not mean it is necessary to expose an imperative API to developers. For example, in the browser, W3C and the browser vendors could have exposed a React-like API, i

Are all the issues with Swift to be expected, or does it seem like there are more issues with Swift than one would normally expect normal from a new programming language?

This is very true. My brother just told me about a class he took on C# in which the teacher gave him a C on an assignment because of 2 things: 1) he had a using statement that reached far into a library, and 2) he used the "var" k

Depending on how it is done, one benefit could be you'd be able to use java/clojure/scala to build command line tools, something few people do now because of the slow JVM startup time.

It only throws if you access the property with the [] or . syntax, so I don't think this particular thing is a big problem.

Om also stores all app state in a single object, but lets you give components a window into that state ('cursors') in order to maintain modularity. If there turns out to be a problem with this general approach, it won't be a

If you have a slow react component that uses mutable data structures for state, and implementing shouldComponentUpdate is hairy, you could always switch to using immutable data structures for that component's state instead. That change
