Express - Framework for building RESTful APIs with Node

 Express (Express.js) is a framework used to build APIs with Node.js. It is an Open source software. It is also useful for building Web-Application. 

It is relatively minimal with many features available as plugins. Express is also the back-end component of popular development stacks like the MEAN, MERN or MEVN stack, together with the MongoDB database and a JavaScript front-end framework or library


Some useful features of EXPRESS helps in API building

  • routing
  • Concentrate on high-performance
  • HTTP helpers (redirection, caching, etc..).
  • Asynchronous programming

It can be installed with the Node Package Manager (NPM).
    
    npm i  -g express

Algorithm solving Common Patterns & Techniques

  These are targeted data manipulation strategies used to handle arrays, strings, and linked lists efficiently. Two Pointers : Uses two reference pointers to iterate through a data structure simultaneously, typically from opposite ends or at different speeds (Fast & Slow pointers). Sliding Window : Maintains a subset of data (a "window") over a sequential structure to track running statistics without recalculating the whole set. Prefix Sum : Pre-computes and stores cumulative sums of an array to allow for \(O(1)\) constant-time range sum queries. Dynamic Programming (DP ): Dynamic programming is an optimization technique used to solve problems by breaking them down into simpler subproblems and storing the results of these subproblems to avoid redundant computations. It is particularly effective for problems exhibiting overlapping subproblems and optimal substructure. Greedy Algorithm Breadth-First Search (BFS) / Depth-First Search (DFS) : Systematic graph and tree travers...
