A recursive function in JavaScript or Node.js is a function that calls itself until a certain condition is met. This allows the function to perform a repetitive task, such as iterating over a list of elements or traversing a tree-like data structure, in a compact and elegant manner.

The Waterfall model is a software development process in which the progress flows in a downward, linear fashion through the different stages of the software development life cycle (SDLC). These stages include requirements gathering and analysis, design, implementation, testing, deployment, and maintenance. In the Waterfall model, each stage is completed before moving on to the next stage, and there is no overlap between the stages. This means that once the requirements for a project have been gathered and analyzed, the design for the project can be completed, followed by implementation, testing, deployment, and finally, maintenance.
The seven stages of the Software Development Life Cycle (SDLC) are as follows:
Planning: In this stage, the project scope, goals, and objectives are defined, and a project plan is created to guide the development process.
Analysis: In this stage, the requirements for the software are gathered and analyzed to determine how the software will function and what features it will include.
Design: In this stage, the software is designed, and a detailed plan is created that outlines the architecture and functionality of the software.
In a programming language, a scope refers to the region of a program where a variable is defined and can be accessed. In other words, a scope defines the visibility and lifetime of a variable. There are generally two types of scopes: local and global.
