A Glossary For Tech Recruiters: Part 3

Tech recruiting

Learning how to ‘speak tech’ is no easy feat. You’re essentially learning a new language, and if you want to source and attract top tech talent, you need to be able to speak that language fluently. If you’ve been following our tech series over the past couple of months, you may have read ‘A Glossary for Tech Recruiters, Part 1 and Part 2‘, both of which listed and explained all of the terms used by developers as well as the most-used technologies in the industry.

Well, the gang at Relocate Me have only gone and done it again! A Glossary for Tech Recruiters, Part 3 is chock-full of the 80 hottest programming trends over the past two years. So if you’re a tech recruiter and you only do one thing today, make sure that you bookmark these posts so that you can revisit them when you’re trying to seek out (and hold conversations with) tech candidates.


  • Angular 2: A JavaScript framework for building complex apps in the browser (and beyond), created and released by Google in Sep 2015.
  • ReactJS: A JavaScript library developed by Facebook for building interfaces which performs on the client side as well as can be rendered server side.
  • Flat UI: A style of interface design emphasizing minimum use of stylistic elements that gives the illusion of 3 dimensions (such as the use of drop shadows, gradients or textures) and is focused on a minimalist use of simple elements, typography and flat colors.
  • V-Model: Represents a development process that may be considered as an extension of the waterfall model and demonstrates the relationships between each phase of the development life cycle and its associated phase of testing.
  • TypeScript: Microsoft’s free and open source programming language that is used to develop JavaScript apps for the client-side or server-side (Node.js) execution.
  • CSS Modules: CSS files where all class & animation names are scoped locally by default.
  • ClojureScript: A compiler for Clojure, designed to emit JavaScript code that is compatible with the advanced compilation mode of the Google Closure optimizing compiler.

  • Relay: A framework for organizing JavaScript apps into scoped modules that are tied to HTML nodes. Allows each view to declare its own data requirements in the form of a GraphQL query fragment.
  • React Native: Allows to build mobile apps only with JavaScript, using native components instead of web components as building blocks.
  • RxJS (the Reactive Extensions for JavaScript): A set of libraries for composing asynchronous & event-based programs using observable sequences and fluent query operators that many of you already know by Array extras in JavaScript. RxJS = Observables + Operators + Schedulers.
  • Bootstrap 4: A free and open-source front-end web framework for designing websites & web apps, that contains HTML- and CSS-based design templates for typography, forms, navigation and other interface components, as well as optional JavaScript extensions. Released in July 2016.

  • Swift 3.0: Swift is a high-performance system programming language which has a clean and modern syntax, offers seamless access to existing C and Objective-C code & frameworks, and is memory safe by default. Swift 3.0 is its major release that isn’t source-compatible with Swift 2.2 & 2.3.
  • Clean Architecture (VIPER): Divides an app’s logical structure into distinct layers of responsibility, thereby making it easier to isolate dependencies (e.g. your database) and test the interactions at the boundaries between layers. VIPER is an application of Clean Architecture to iOS apps.

  • PHP 7: It’s still in the development phase, the final version will be released in November under the code name of PHP#NG (Next Generation). But the feature-complete beta of the new PHP 7 is already available. Among the advantages of the new PHPNG engine are: twice speed (your code will be executed faster but you will need fewer servers to serve the same amount of users); 64-bit Windows Systems Support; an opportunity to use anonymous classes, a well-established practice in other object-oriented languages like C# & Java.
