What makes a good and consistent code?
Static code analysis
Code style guide
Code-nazi in your team
Code review
CI/CD
It is always good. But...
Not always easy to setup
Requires extra tooling and effort
Slows down initial development cycle
Thus [almost] always skipped at the start
And that is OK, because...
Compiled languages
Javascript naturally came to be compiled first... At last!
Remember CoffeeScript
And why it was not OK?
Sourcemaps!
Now you can compile JS and debug it with sourcemaps
With any syntax you like
JSX
ES6. And ES7. Why compiled?
Babel JS
https://babeljs.io
Webpack
https://webpack.github.io
ESLint
http://eslint.org/
ESLint React plugin
https://github.com/yannickcr/eslint-plugin-react
Let's bring it to the compilation!
Simple React app
npm start
Let's change some code
What if I make some mistake?
