In the 90\u2019s we were witnesses of browser wars. Wars which created one of the most hated languages: Javascript.<\/p>\n

Web designers touch by Javascript at the beginning of 21st century constantly refused to fix bugs titled as \u201cIt doesn\u2019t work in Internet Explorer\u201d or \u201cNetscape Navigator doesn\u2019t show\u2026\u201d.<\/p>\n

At this time we used pure languages and tried to understand the design of our web browser in order to cope with compatibility issues.<\/p>\n

Thanks to DOM, DHTML and Ajax, JavaScript went to another level. It became \u201clingua franca\u201d for those who wanted to create dynamic web pages not web business cards. Now, with Node.js, we can also implement server-side applications in Javascript.<\/p>\n

So, why we do we hate it so much?<\/p>\n

Why I don\u2019t hate Javascript anymore<\/h2>\n

When I start to speak about JavaScript with people focused on another language e.g. Java I can hear some noises of pain, discomfort or a tortured human being. Aversion to Javascript was probably imprinted in all software communities during 90\u2019s and it infected next generations. I understand that maybe in 2005 writing JavaScript code was still a painful process, because of insufficient tools, meaningless error messages and slow engines. JavaScript is no longer a slow and clumsy brother of Java.<\/p>\n

I\u2019ve got a framework<\/h3>\n

Without JavaScript it would be impossible to create dynamic applications. Document Object Model (DOM) gave us the possibility to respond to user interaction in the same way as in a desktop application. JQuery-like libraries created a layer of abstraction above DOM and they enriched web elements with behaviours. That wasn\u2019t enough for Javascript developers. More complex web sites required better structure of source code. The answer for this was the need of a JavaScript framework.<\/p>\n

Javascript frameworks organise code and simplify interaction with web browser. Some of the more popular ones being AngularJS<\/a>,Backbone<\/a>, Ember<\/a> or Knockout<\/a>. They base themselves on the MVC model and models derived from MVC. If you don\u2019t like the approach represented by them you can choose more exotic frameworks such as Polymer<\/a> and React<\/a>.<\/p>\n

I\u2019ve got a test<\/h3>\n

The source code cannot exist without tests. QUnit<\/a>, Jasmine<\/a> or Mocha<\/a> are unit test frameworks that can help you to test your code. Unit test libraries already provide basic assertions, but you can extend this functionality by using chai<\/a> or should.js<\/a> libraries. If you want to use mocks, stubs and spies in your code, there are libraries for that too (e.g. sinon<\/a>).<\/p>\n

Node.js is the best choice if you need some environment to run tests. Karma<\/a> or Testem<\/a> give us possibility to verify behaviours in web browsers. Tests can be also executed as part of a Continuous Integration pipeline using a headless browser (PhantomJS<\/a>).<\/p>\n

I\u2019ve got a choice<\/h3>\n

If you still don\u2019t like JavaScript, you can find languages that can ease you into it. CoffeScript, TypeScript, ClojureScript and Dart are languages which introduce syntactical sugar and they are transcompiled to JavaScript.<\/p>\n

Embrace JavaScript<\/h2>\n

Currently we don\u2019t have better alternative for JavaScript in web browsers. Until then we can make our lives better by embracing it, knowing that at times it can be ugly and harsh. Be kind to the unwanted child of the browser wars.<\/p>\n
