Why? Typescript transpiles into js but maybe the transpiler intruduces some overhead, isn’t it possible? I am not familiar with these languages, so this is an honest question.
It’s barely transpiled. There are a couple of features that involve actual code generation - enums and namespaces (which are almost never used), but the vast majority of it is just stripping the type annotations so the performance will be 100% identical.
It’s like having “Python” and “Python with type hints” as separate languages and claiming there is a big speed difference between them.
Stop linking this, please! Any benchmark where Typescript and JavaScript are different is trash.
