Suppose there is a function with lots of arguments but you need to change only one or two argument every time you use that function, Partial function comes to the rescue.

Take advantage of the heapq module to implement a Priority Queue — What is a Priority Queue? A Priority Queue is a type of queue in which every element is associated with priority and it returns the element of highest priority on every pop operation. if priority is same the elements are return on basis of their insertion order. We can easily implement priority queue in Python…

Make your code more functional. Object oriented programming makes code understandable by encapsulating moving parts. Functional programming makes code understandable by minimizing moving parts. — Michael Feathers map, filter and reduce are essentially just some of the most well-known, easy to use, higher-order functions that run provided callback on each…

Understand the different usage of function in JavaScript In other object oriented programming languages Function, Method and Constructor call may be different things but in JavaScript these are just different usage pattern of one programming construct — Function.
