Most applications aren’t written to compile deterministically so there is always a chance.

Compile? Is that true? Pretty sure compilers are generally deterministic in their output.

Mainly making a joke that they aren’t binarialy deterministic. Semantically they are though.

Hmmm would most code these days be compiled into minified JavaScript? That might be more deterministic.

JavaScript is what is called an interpreted language there is no compiling at all the code is directly read and interpreted at runtime. Most of the time it’s minified which reduces the size. Or in the case Vue React or Angular is transpiled which still results in JavaScript code but framework specific syntax is broken out and it’s ran through bable to do backwards compatibility for older browsers.

Isn’t Typescript compiled into JavaScript?

Technically transpiled. Compiling results in something binary.

No a compiler just translates from one language into another. Transpilers are a type of compiler.
