Synechron interview question
what is currying in the javascript Currying is a technique used to transform a function with multiple arguments into a sequence of nested functions, each taking a single argument. The curried function returns a new function for each argument until all arguments are provided, and then it finally returns the result. This technique allows for partial application of a function, meaning you can pass some arguments now and the rest later.

Explain the JavaScript patterns Module Pattern: Encapsulates private and public members using closures. Promotes modular code organization and prevents pollution of the global namespace. Singleton Pattern: Restricts instantiation of a class to a single instance. Provides a global access point to that instance. Observer Pattern: Defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. Promotes loose coupling between objects. Factory Pattern: Encapsulates object creation logic and provides a generic interface for creating objects. Allows code to interact with objects through their interfaces rather than their concrete implementations. Revealing Module Pattern: A variation of the Module pattern where all methods and properties are defined in the private scope and are revealed as public members at the end of the module.
