New technologies for the Capital Markets

JavaScript has been around for over 20 years, but it wasn’t considered a real contender in the realm of programming languages until about five years ago. The maturity of browsers and the release of Chrome JavaScript V8 Engine have both played a big role in the growth of JavaScript as of late.

With the evolution of client-side frameworks and libraries – like angularJS, Backbone.js, Ember, React and server-side JavaScript, to name a few – developers are now building large-scale JavaScript applications with drastically lower overhead. These technologies help trim down application scopes and timelines by providing great API’s and structural architectures to deliver an advanced starting point.

Many companies are leveraging this power by building their applications utilizing MongoDb, Express, AngularJs and Node.js, otherwise known as MEAN stack. Some of the advantages of MEAN stack are:

  • One language for front-end and back-end development.
  • Operating system flexibility.
  • Supports the MVC (Model View Controller) architecture.
  • With Javascript as the underlying language, it is easy to find developers able to build and maintain your application.
  • Open source components.
  • MongoDb is JSON-based, which JavaScript developers are very familiar with.
  • Gets projects off the ground quickly and painlessly.

It is worth mentioning that, although all of these technologies use JavaScript, not all JavaScript developers have experience with the entire stack.

The division between client-side (AngularJs) and server-side (Node.js) development still exists, as each requires its own skillset and expertise. To improve programming efficiency, firms should invest in developers versed in both front and back-end code.

It’s increasingly clear why MEAN stack has gained so much popularity and serious consideration when building applications. MEAN has been particularly popular where a premium is placed on being first to market with limited resources, such as startups and large ecommerce companies.

As a consultant, it is important to educate yourself in the upcoming trends to best understand where your field is headed. MEAN might not be here forever, as Express and AngularJs will eventually be phased out by newer and more powerful frameworks, but I believe end-to-end JavaScript will be here for a long time.

In this era of web 2.0, speed is critical across industries, and the Capital Markets are no exception. I can see this trend carrying into the financial industry as more FinTech companies look to tackle old problems with a new approach.
