TypeScript Consulting

  • TypeScript is type-safe JavaScript that allows code reuse. Imagine upgrading to the latest version of ECMAScript with just one line of code.
  • At Cazton, we help Fortune 500, large and mid-size companies with TypeScript development, consulting, recruiting services and hands-on training services.
  • We can help you with performance improvement, code quality, code coverage, CI/CD and implementing TypeScript best practices.

It is no secret JavaScript has become insanely popular amongst developers. From backend engineering to building hybrid mobile apps and constructing cloud solutions, it has made its massive presence felt everywhere. Even the fields of machine learning and robotics started adopting the versatile JavaScript.

Naturally, the quest of making it more reliable and robust began. The result of this effort was TypeScript. TypeScript is JavaScript that is developer friendly and makes the code more maintainable and scalable. It enables developers to write code that follows industry standards, design patterns and practices and create top-notch solutions using high-development development tools. It is the language that supports previous, present and futuristic features of ever-evolving JavaScript and can run on any browser, host or Operating System.

TypeScript gained popularity when Google used it for building the very famous Angular framework from scratch. Our team at Cazton has the expertise from traditional to the latest technologies backed with years of rich experience developing scalable and modular applications that are easy to test and maintain. We also offer TypeScript training where we cover everything you need to know from the basic to advanced.

About TypeScript

TypeScript is a superset of JavaScript. All JavaScript code is also valid TypeScript, but TypeScript contains additional syntax and functionalities not available in some old versions of JavaScript.

JavaScript is a dynamic language and everything in JavaScript is dynamic. It places no stringent checks on the values imparted to its variables. One can create new variables at runtime and the type of variables is determined at runtime. One can also create new functions at any time, or replace existing functions. When used in a browser, code is added when more script files are loaded and you can load more files any time you like.

TypeScript enjoys the benefits of both worlds (static and dynamic typing). By default, TypeScript does not enforce type annotations, which means that the code is valid and will execute even if you do not assign a data type to a variable. Type inference takes care of it. Of course, to do so would be underutilisation of its true potential.

By enforcing type annotations, your TypeScript code not only becomes scalable and maintainable, but also helps to reduce code defects. It offers many other benefits beyond the multi-featured Javascript. Let's explore more of the TypeScript benefits.

Features and Benefits of TypeScript

Known for being a feature-heavy language, here are some of the features of TypeScript that draw developers to it:

  • Backward compatibility with JavaScript: A client of ours expressed reservation moving to TypeScript as they had 4 million plus lines of JavaScript code. They were thrilled to know that TypeScript understands JavaScript as it is and no immediate change needed to be done with the legacy code. Over a period of time, we eliminated a lot of redundant code and reduced it into less than half a million lines of TypeScript code. This is the power of TypeScript!
  • Object Oriented Programming: It supports Object Oriented programming concepts like encapsulation, abstraction, inheritance and polymorphism which helps developers from a C# or Java background get accustomed to TypeScript quickly.
  • No overhead: TypeScript is portable, meaning it can run on any device, operating system and browser. However browsers cannot understand TypeScript code and hence, it needs to be transpiled to JavaScript first. Transpilers like Babel are available that can help transpile TypeScript code to JavaScript. There is zero loss of performance as the deployed code is nothing but JavaScript.
  • Static Type Checking and Error Susceptibility: The highlight feature of TypeScript is optional static typing. Developers get the option to enforce static typing and assigning type annotations while coding. This not only makes TypeScript code scalable and maintainable, but it also helps in reducing code defects.
  • Developer Friendly: Other than its feature of unconditional static typing, developers can use any IDE of their choice and write TypeScript code. All latest and famous JavaScript frameworks like Angular, Vue, React, Aurelia support TypeScript, which means developers can create apps offering rich user experiences, using this language.
  • Deploy in any version of ECMAScript (or JavaScript): This is one of the major benefits of TypeScript. TypeScript provides access to ESnext features before they become supported by major browsers. Developers can code in TypeScript and with just one line of configuration change, the code can be deployed in any version of ECMAScript. Imagine moving your code from ES5 to ES 2016. It's not an easy task. ES5 was very functional and didn't have any support for classes. If that code was written in TypeScript, all you had to do was change the configuration to ES 2015 and TypeScript would convert that code for you. This is an immense benefit considering the fact that this will also allow for future versions of ECMAScript that are not yet released.
  • Design Patterns: If you are from an Object Oriented background and have used languages like C# or Java, you very well realize the benefits of using design patterns to make your code better. Even though JavaScript doesn't have interfaces, we can now create TypeScript Interfaces that make our code much simpler and modular.
