What is the difference between a compiler and an interpreter? What characteristics of an interpreter make it better suited for executing JavaScript programs?

What will be an ideal response?


A compiler is a program that translates an entire high-level language program into its equivalent machine-language instructions. In contrast, an interpreter translates and executes the statements in the high-level language program one statement at a time. While this can make the execution of programs slower, it does provide immediate feedback as the output of statements can be displayed as they are executed in turn.
