javascript-learning
My learning experience of javascript language.
This code is based on exercises from javascript.info and "Eloquent JavaScript" book by Marijn Haverbeke.
How to run script:
yarn run babel-node src/arrays.js
How to monitor flow via flow-watch: this will constantly monitor code for
flow errors
yarn run flow-watch
How to run jest tests on every change:
yarn run jest --watchAll
Setup instructions
To create new javascript template project with babel support, flow typing and jest tests - use these yarn modules:
yarn add --dev @babel/core @babel/cli @babel/preset-flow
yarn add --dev @babel/node
yarn add --dev jest
yarn add --dev babel-jest babel-plugin-transform-flow-strip-types
What's the right way to write Jest tests verified with Flow? https://stackoverflow.com/a/50805762/2075157
- Check jest version
npx jest -v
- Install flow-typed
npx flow-typed install jest@24.9.0
- Add flow-typed in .flowconfig file
