rand VS yew

Making compatibility promises for distributions means they cannot take advantage of potential advancements in the field.

Defining an error type that is meaningful, portable, and compatible with no-std isn't straightforward. If the std lib's getrandom requires std, then just like that, rand and many other crates won't use it anyway. Using io::Result seems to me to face this challenge.

Some wasm targets can’t generate random numbers at all but in the case of the book because you are using wasm in a browser you can use JS to generate random numbers. I believe there’s a way to get the rand crate to use JS as the backend for generating rand but its a bit more convoluted than the easy one-liner that the book suggests.

rand

This uses rand and xcomplex to handle the mathematics, png to write image files, and dialoguer and indicatif for some pretty prompts and progress bars.

You can often achieve this without any unsafe by putting an assert!() on the length before the hot loop. For example, I got rid of some unsafe in rand that way.

This is a widely used method to map random integers to floating point numbers, but it has the disadvantage of wasting 1 bit of float mantissa precision.

On modern CPUs, its computational advantage over full-precision mapping methods, such as multiplication by a float, is not always clear [1].

In fact, there are a lot of crates in Rust where in other programming languages, it would be included in the standard library. Examples are regex, random number generators, additional iterator methods, macros for other collections, num traits, loggers, HTTP libraries, error handling, async runtimes, serialization and deserialization, date and time, and many more.

I coded up a game of life implementation in rust and web assembly using https://yew.rs/ as an effort to sharpen my rust skills and it resulted as a fun toy. You can find the source here: https://gitlab.com/reedrichards/wvdom Enjoy!

UI template: Yew - (https://yew.rs/)

I'm surprised nobody said they'd use [Yew](https://yew.rs/), especially given the premise of this being for a passion project.

This example shows updating an existing state: https://github.com/yewstack/yew/blob/04909dd942eb64285652d96a2621bdf7be3fa912/examples/timer_functional/src/main.rs

1. Not related to npm, but related to the web.

2. True, but compilers are generally better than transpilers.

3. Have you seen https://yew.rs/ ?

You could use Yew to write web apps, which can be opened on Android phones.

What about Yew and Iced?
