Starting with React is quite easy. You just need to install the npm package and can create your components. However, unlike Angular, React is not providing a whole ecosystem which comes with a architecture and everything necessary like router, module system, components, templates already prepared for immediate start. Angular is a framework, whereas React is a library for creating ui interfaces! This is a huge difference (framework vs. library). In this short article I show an example architecture which you can use, if you don’t know how to structure your app.

PHP: Installation of newest package version vs. update package
There is the little bit misleading composer command: composer update. It also allow to only update 1 to n packages with composer update package1 package2 (package names as arguments.

If you are writing tests and have string comparisons done, it can be sometimes tricky. Common problems are:
- character encoding, eg. UTF-8 vs. ISO 8859-15

- non-breaking space characters, eg. in the example above between amount and currency
