Code can be stink and you need to know how to identify them and make a refactoring to reduce the technical debt. A software application with huge technical debt is difficult to survive in long term. Lets learn how to identify and thus fix them. Bloaters When a method,class, parameter list…

It is fine if we do not KNOW everything but we must master the basic stuff. With robust base knowledge, your coding skill will be MORE convincing. Thus, fundamental knowledge questions always be the first stage in the technical interview. 1. What is the difference between ‘===’ and ‘==’? It is about type coercion. However, if the candidate talks…

Purpose Time complexity measures the total time taken to execute each of the statement of an algorithm. Space complexity measures the total amount of memory space used to run a algorithm including the inputs. Why are they essential? There are millions ways of coding to achieve the same target. However the time and space taken…
