In computer science, compile time (or compile-time) describes the time window during which a language's statements are converted into binary instructions for the processor to execute. [1] The term is used as an adjective to describe concepts related to the context of program compilation, as opposed to concepts related to the context of program ...
Runtime, run time, or execution time is the final phase of a computer program ' s life cycle, in which the code is being executed on the computer's central processing unit (CPU) as machine code. In other words, "runtime" is the running phase of a program.

In computer programming, a runtime system or runtime environment is a sub-system that exists in the computer where a program is created, as well as in the computers where the program is intended to be run. The name comes from the compile time and runtime division from compiled languages, which similarly distinguishes the computer processes ...
However, dynamic compilation can still technically have compilation errors, [citation needed] although many programmers and sources may identify them as run-time errors. Most just-in-time compilers, such as the Javascript V8 engine, ambiguously refer to compilation errors as syntax errors since they check for them at run time. [1] [2]
Type enforcement can be static, catching potential errors at compile time, or dynamic, associating type information with values at run-time and consulting them as needed to detect imminent errors, or a combination of both. [1] Dynamic type enforcement often allows programs to run that would be invalid under static enforcement.
In computing, compile-time function execution (or compile-time function evaluation, or general constant expressions) is the ability of a compiler, that would normally compile a function to machine code and execute it at run time, to execute the function at compile time.
In computer programming, a runtime library is a set of low-level routines used by a compiler to invoke some of the behaviors of a runtime environment, by inserting calls to the runtime library into compiled executable binary.
