It is a must for a JavaScript Developer to use appropriate frameworks for mid to long term projects. The web development company actually needs to put in the effort in planning and specifications before actually getting work started. But the way a JavaScript developer will go about the actual web development work will makes a real difference in the long run in terms of quality. This also somewhere describes the quality and skillsets of the JavaScript developer.

As JavaScript applications are becoming more complex in development and execution, unit testing by the JavaScript programmer themselves and quality assurance personnel is becoming more important. Whether the web programmers prefer or the client suggests QUnit, or Mocha, or any of other JavaScript testing frameworks out there, the web developers should write the tests first and then write functional codes to pass those tests.

As any technology even JavaScript development has evolved and progressed over a period of time. Several years back, web programmers at every web developer company would write lines and lines of codes to do every simple task - for e.g. typical registration, contact us forms or simply creating rollover image effects for creating good looking navigation menus etc. But in today’s time, a large amount of frameworks have been built and used to handle simple as well as complex tasks. E.g. jQuery for the standard date picker and modal effect requires a lot of code going behind it. In fact, basic features such as a date picker could also be fairly achieved by using smaller plug-ins that can be used universally across the project as desired.
