Interpreters offer more functionality by allowing users to run a program without having to fully compile it first. This makes the program faster and more efficient in terms of execution, as it can be run repeatedly and does not need to be recompiled each time.Ĭompilers are often used for larger applications, as they can take longer to compile but generate more efficient code. It reads the entire source code and, if there are no errors or warnings, compiles it all into an executable program. A compiler is a program that translates code written in one language to another, typically a low-level language like assembly, so that it can be executed by a computer.Īn interpreter executes code directly, translating one line of code at a time.
