| // They’re an idiomatic way of representing data using “ands” and “ors”. For example: | |
| // a shape is a rectangle or a circle | |
| // a rectangle has a width and a height | |
| // a circle has a radius | |
| // In ADT (Algebraic Data Types (ADTs))terminology, “and” types such as rectangle and circle are products, | |
| // whereas the “or” types such as shape are coproducts. | |
| // In Scala, we typically represent products using case classes and coproducts using sealed traits: |

| Nodejs is javascript engine from Chrome V8 Engine . | |
| Which runs javascript code in the backend | |
| node js is non blocking io module ie., if any lines takes more time , than the cpu does not block other lines and continues execution of other lines | |
| npm - package manager for js .Similar to pip in python | |
| Note: Never push node module dependencies to Git as it is huge | |
