For the first operation of NEW button – generating components – we add mutation to our store.js mutations: { addJob (state) { state.jobs.push(state.jobs.length + 1) … } Second, creating local modules. Here we’re going to use reusableModule to generated multiple instances of a module. That module we keep in separate file for convinience. Also, note … Read more
Can I use “a” variable in a global scope after module importing or is it available only in a module scope? It’s only available inside the module it was declared in. Will ES6 modules have a similar working principle like this trick: […] Basically yes. ES6 has these kinds of scopes, order from “top” to … Read more

Flask uses the import name to know where to look up resources, templates, static files, instance folder, etc. When using a package, if you define your app in __init__.py then the __name__ will still point at the … Read more
