Building a complex web front-end application? Want a single modular framework to handle everything? AngularJS is a popular enterprise framework to build and maintain complex websites. It’s good enough for Domino’s Pizza, iTunes Connect, PayPal, Google and a bunch more. Bet it’ll do the job for you, too.
AngularJS is a Model-View-Controller (MVC) type framework:
- Create two-way data binding between models and views, for automatic updates when data changes
- Build reusable view components to save time
- Easily enable backend and frontend servers to stay synchronized
Vue is a lightweight alternative to AngularJS. Vue is a library focused on view layer only. It will keep what you see on the screen synchronized with the data model. Use this framework to create simple and flexible views without the overhead of a larger framework.
- Leverage your existing HTML skills
- Extend HTML’s syntax to clearly and succinctly describe your components
- Reduce code you write, while AngularJS dynamically injects code for you
There’s more, plenty.
The frameworks above represent some of our favorites. Others to consider include JQuery, Ember, Redux, MobX, KnockoutJS, BackboneJS, DurandalJS and plenty more.
Skills and qualifications
Find out about these for your candidate developer (and build up this list for your needs):
- What is and how can you reliably test if a value is equal to ‘NaN’?
- What is functional programming?
- What is the difference between classical inheritance and prototypal inheritance?
- What are the pros and cons of functional programming vs object-oriented programming?
Obviously, these are just a few questions to learn more about your candidate developer.
