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 ] Examples

A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
This example specifies a valid D function called "factorial" which would typically be evaluated at run time. The use of enum tells the compiler that the initializer for the variables must be computed at compile time. Note that the arguments to the function must be able to be resolved at compile time as well. [4]
The function head() returns a list containing the first element in the list. The function tail() returns a list containing everything but the first element. The function cons() returns a list that is the concatenation of other lists. Therefore, the following expression will return the list x:
process.h is the C header file which contains function declarations and macros used in working with threads and processes. Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell NetWare or DOS extenders supply this header and the library functions in their C library.
The heuristic function is then used at runtime; in light of the code behavior, the allocator can then choose between one of the two available algorithms. [ 51 ] Trace register allocation is a recent approach developed by Eisl et al. [ 3 ] [ 5 ] This technique handles the allocation locally: it relies on dynamic profiling data to determine which ...
Further benefit can be derived from replacing the modulo operator with an equivalent function tailored to this specific case—for instance, a simple compare-and-subtract, since the quotient never exceeds 1. [5] Here is a C implementation that applies the first but not the second optimization:
