TASK 2
ASYNC JS :
Learning about asynchronous javascript and implementing a small callback function which means a function which is passed as an argument to another function , when the outer function is called the inner function is also called . for large programs due to complex nesting as arguments the program becomes difficult to debug and creates a situation called callback hell. here is a program which displays recipe using callback function. link for code and execution : https://github.com/MPSAJID/Marveltasks/tree/main/TASK2
TASK 3
PROMISES :
As the callback programs create callback hell ,PROMISES solve this issue.promise is an object returned by async function which represents the state of the operation ,also promises are easier to nest and easier to identify the errors in the code. the same recipe program is implemented using promises. link for code and execution : https://github.com/MPSAJID/Marveltasks/tree/main/TASK3
