Software Testing helps ensure quality, prevent bugs, reduce development costs, and improve performance. Both inspection and testing are important methods to detect defects. When I just started my software engineering career, I had always heard different terms for the type of testing but got confused about what these tests really…

A “high-level single-threaded, garbage-collected, interpreted (or just-in-time compiled), prototype-based, multi-paradigm, dynamic language with a non-blocking event loop” language — JavaScript is an interpreted language, it needs an interpreter in the environment to read the source code and execute it, whereas languages like Java and C are compiled languages, that statically analyze all your code in advance, and compile it down to binary which you can run in the machine.

Refactoring is a systematic process of improving code by transforming the messy dirty code into clean code and simple design that is easy to read, understand, and maintain to fight technical debt. Following the Best Practice Principles KISS: Keep It Stupid Simple DRY: Don’t Repeat Yourself SOLID: Single responsibility principle, Open–closed principle, Liskov substitution principle…

Use CSR if a site is under development, like a dynamic SPA handled by React Use SSR if a site is stable, static, SEO focused, can pay for additional services Use NextJS if a site is built as SPA for fast interactive UI but needs SSR feature Server-side Rendering The initial load…

The software architecture of a system represents the design decisions related to overall system structure and behavior. The design goals should be set as the guidelines for design. Nonfunctional requirements usually help define design goals. MVC: Model, View, Controller The Model, the application object. The View, the screen presentation. The Controller, the way the…

Software Engineering is a systematic approach to the development, operation, and retirement of software. Software process has a positive effect if applied correctly, meets schedules, has higher quality, and is more maintainable. We always want to produce high-quality products with all features with less time and cost. However, there are…

For an overview of all 23 GOF Design Patterns, Read more …

Object Oriented Design (OOD) Identify domain classes/objects — Real-world objects or concepts in the application, bridge the gap between high-level requirements and design. Design patterns provide a shared vocabulary to solve common problems. Frameworks make use of design patterns in their implementation. The Gang of Four (GoF) Summarize Object-Oriented Design in OOP — 23 Software Design Patterns Each in…
