For the past few years, TypeScript has grown in popularity. It is listed as one of the five most promising languages for the year 2020. In addition, typeScript is used by Angular, one of the most popular frontend frameworks. Around 65% of JS developers currently use TypeScript.
TypeScript is a programming language
Making types clear directs our attention to the details of our system’s construction and the interactions between its many components. It is critical in large-scale systems to abstract away from the rest of the system while keeping the context in mind. This is made possible through types.
TypeScript provides the concept of static solid typing as an optional feature: Once defined, a variable retains its type and may only accept specific values. In addition, the compiler notifies developers of type-related errors, preventing them from progressing to the production phase.
TypeScript finds 15% of typical problems at the compilation step, according to researchers. While this is far from a perfect outcome, it is large enough to save engineers time and allow them to concentrate on resolving logic errors rather than identifying common defects. Additionally, submitting the code to a compiler reduces the number of quality assurance and testing tasks.
With TypeScript, everything is preserved in its original state. For example, if a variable is defined as a string, it remains a string and never be converted to a Boolean value. This increases the chances that functions will perform as intended.
Due to the addition of strict types and other self-expressive aspects, you can discern the developer’s design intent when the code was initially written. This is particularly critical when distant teams collaborate on the same project. Thus, a self-contained codebase may compensate for the absence of direct contact between team members.
TypeScript supports class-based object-oriented programming (OOP) principles such as classes, interfaces, and inheritance. The OOP paradigm helps develop well-organized, scalable code, which becomes more apparent as your project develops in size and complexity.
Type information makes editors and integrated development environments (IDEs) far more helpful. They may include capabilities like code navigation and autocompletion, which provide precise recommendations. Additionally, you get feedback when typing: The editor immediately indicates any mistakes, including type-related ones. All of this contributes to the development of maintainable code and resulting in a considerable increase in productivity.
In general, TypeScript is an excellent tool to have in your toolbox, even if you are not using it to its full potential. It is simple to start small and expand gradually, learning and adding new features along the way. There is no need to be terrified of TypeScript since it is pragmatic and inviting to newcomers.
