Tser's grammar support will continue to improve. Refer to the _test file in the directory. Similar products: AssemblyScript、 StaticScript.
Antlr 4 install for mac code#
The Tser's front-end relies on the syntax parser generated by Antlr, and then generates and traverses the syntax tree the back-end relies on LLVM construction, compiling TS code into LLVM IR, and using its JIT engine to immediately execute IR. Tser can do very little at present, because the syntax support is very imperfect, and can only support the execution of some simple scripts, for example, it may be able to support some simple cloud function scenarios. When the grammar support is complete, and most of the existing background services written in TS can be run, then these services can get a great performance improvement. Tser has relatively low compilation performance and high runtime performance, which is more suitable for scenarios such as independent background services and serverless. TS may never be able to replace the JS ecology, but in some areas, TS can exist independently of the JS ecology the TS virtual machine is the cornerstone of the independent TS ecology, allowing TS to have significantly better runtime performance than JS in these areas, and Bring real business benefits to these areas. When we thinking about the development of TS technology aside, where will it end? Will it stay on a pre-compiled language? When the TS ecosystem develops more and more sound, is it necessary to rely entirely on the JS ecosystem? Will there be a real TS virtual machine (Deno is not)? If the industry has a stable and high-performance TS virtual machine, is it a good thing for the TS ecosystem, and will it push TS to a new level? TS technology has developed rapidly, and more and more projects in the web industry have been developed and refactored using TS. Test conditions: the same device in the same state, none of the compilation processes usded optimization). Let’s look at a set of performance comparison data, only comparing the performance of fib(42) in each virtual machine or language (It cannot be completely regarded as a performance evaluation standard. TS itself is a statically typed language with certain data type declaration, but the type declaration is lost when escaping to JS if we can directly execute the TS program instead of first escaping to JS and then executing, the data type declaration can Brings a great performance improvement to the program. Due to its strong dependence on JS, it cannot get rid of some of the stubborn problems of JS, such as execution efficiency. TS is essentially a pre-compiled language, executed using the JS virtual machine after compiled into JS. TypeScript (TS) is a greate invention, for letting us have a statically typed language development experience while reusing the JS ecosystem. $ brew tap tser-project/tser & brew install tser
