How to improve page load speed and response times: A comprehensive guide
Minification involves removing unnecessary characters, whitespace, and comments from code files. It helps reduce HTML, CSS, JavaScript, etc., file sizes without compromising functionality. Removing redundant elements makes these HTML, JavaScript, and CSS files smaller. Since smaller code files need less internet traffic to transfer, they load faster. Utilizing tools like UglifyJS, Clean-CSS, and HTMLMinifier enhances this process of code reduction. They analyze the code, remove redundant code, and generate optimized files for deployment.

Overview of the next-gen frontend dev tools
There are many minifiers such as terser and uglify. But, because minifying also require to parse the JS, it is actually possible to use esbuild and SWC to minify the code. Here's a benchmark of the main minifiers.

JavaScript and CSS minification.
In my understanding, UglifyJS 3 is the most popular JavaScript minifier tool presently -- it has a very high weekly download too. And as per the official documentation, it supports ES6.

Enhanced noise suppression in Jitsi Meet
I'm thinking reverse-engineered uglified js code (https://github.com/mishoo/UglifyJS) is not as impenetrable as code from reversed engineered wasm binaries? The element of plausible deniability is much more potent though, for the nefarious actor on the other side.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation
