What Does Break-Even Point Mean?
A programming language is said to reach a “break-even point” when it can be implemented in itself. For example, a Lisp interpreter that is written in Lisp as well. One major goal for a new programming language is to reach the break-even point, as it is easier to ship programming tools if they do not depend on another language.
Techopedia Explains Break-Even Point
The break-even point is when a programming language can be implemented in the programming language itself. For example, a C compiler might be able to compile its own C source code. New programming languages are often written in an existing language. Reaching the break-even point allows a developer to ignore the original implementation and focus on developing a new language.
