This is when things become complicated.
The TypeScript compiler informs the IDE about many aspects of TypeScript, which is partly why TypeScript is so popular.
This provides various benefits to the user.
For one thing, faults are easy to spot. While coding, compilation failures are indicated by a red line in the IDE. And, thanks to code completion, you can get inline guidance when you have queries about what functions a library might provide. This improves workflow by eliminating the need to pause and seek assistance from other, online resources.
This improved IDE support, when combined, increases overall user productivity.
In other circumstances, though, this may be too late. Furthermore, assuming a variable to be a given type incorrectly can lead to serious errors.
TypeScript facilitates error checking.
TypeScript will detect syntax issues and alert users by creating compilation errors as it compiles the code. Thus, TypeScript allows users to catch bugs during the compilation process rather than waiting till runtime.
In this regard, TypeScript's class feature was a preview of what to expect from ECMAScript 2015. Optional static typing (also known as gradual typing), which allows static language analysis to increase tooling and IDE support, is a unique feature that was added to TypeScript rather than proposed.
This is in stark contrast to many TypeScript competitors, which require a dedicated virtual machine or specific runtime settings for execution.
Support for robust developer tools Overall, TypeScript promises to increase developers' efficiency and productivity by reducing errors, assisting with problem-solving, and providing better tooling at scale.
TSC is particularly useful for developers because it may be performed in the background to support compilation and IDE integration.
