JavaScript's role in web development has gone from being considered a starter language for hobbyist programmers to being regarded as a serious tool for building modern web applications on both the client and server. This change means that the size and scope of JavaScript applications has grown tremendously, and with that growth, the costs for managing the complexity have also increased. To address this, Microsoft has developed the open source project TypeScript, which is a superset of JavaScript that adds static type checking.
The result is that TypeScript can be used to build a new web application from the ground up just as well as it can be used on-demand to replace or refactor code in an existing JavaScript project. TypeScript can help depending on the needs of your project. Let's take a look at how TypeScript can benefit your web application.
