Is javascript interpreted or jit compiled

I am new to programming. And i am following a tuturial about javascript. But i am confused with jit compilar and a interpreter. Is javscript translated from source code to byte/native code. With a jit compilar or a interpreter? Or depends from the browser and the javascript engine you are running.

Thank for your respons

    JavaScript is scripting language and browser is executing scripts which are in text format. So by definition that makes JavaScript interpreted language.

    Compiled languages are those which are executed from binary files.

    JIT compilation is just something that JavaScript engines can do as way of optimization, but you never truly generate binary JS files, so language is interpreted one.

    Javascript is an interpreted language.It is directly interpreted by browsers for execution.

    But,modern browsers support JIT compilation which converts it to bytecodes for high performance.
