Question

Write a 200 word paragraph answering these questions Which languages have you used which have dynamic typing? Which have explicit typing? What are the downsides of dynamic typing? What are the benefits? this is a Computer science question.

Answer 1

First of all we need to understand what dynamic and static typing means . Here "type" refers to the definition of the data type and not the keys typed on the keyboard . In static typing the variable must be defined before they are used that means they should be initialised or declared and then they can be used in the program . Java , C , C++ are examples of static programming . In it the type is checked at compile time while in dynamic typing the type of variable is checked at run time . In dynamic typing the prior declaration of variable is not needed before using them . eg Python ( val = 30 // directly using the variable), Javascript.

The main disadvantage of using dynamic typing is that the error in the program will be detected at a very later scale . The possibility of errors at runtime is not healthy practice for the development team . Moreover to check for the data type errors the mechanical testcases have to be written . But there are greater benefits of using dynamic programming . It avoids repetition of code to a great extend and removes the redundant declarations . The code is shorter and the compile time is less. It is quicker to read and easier to implement.
