Around 2010, Microsoft noticed something strange. Some of its teams were using a community project called Script# (ScriptSharp) to build JavaScript apps. The Script# library allowed for developers to write code in C#, which would then be transformed into JavaScript. There are a lot of benefits to writing code in a strongly typed language like C#. When you make silly errors like misspelling a variable name, you’ll get a warning right away instead of finding out when the build doesn’t work. More importantly, refactoring code in a strongly typed language is much simpler. If you needed to change how a function was called, this could be done in a few clicks instead of a few hours. By comparison, writing in JavaScript felt like carving your code in stone tablets. Once written, it was hard to change. Microsoft tasked Anders Hejlsberg, the creator of C#, with investigating Script#. He was surprised to find that people were so annoyed with JavaScript that they were willing to code in a completely different language to avoid it. However, he found the combination of C# and the Script# library bizarre. Wouldn’t it make more sense to create a new language that was closer to JavaScript and enabled developers to use all the IDE features that JavaScript was missing? And so, TypeScript was born. In the decade or so since its introduction, TypeScript has become a staple of modern development. It’s been adopted by huge companies like Google, Netflix, and Airbnb. Teams that use TypeScript ship better software at greater speed—and are happier as a result.
