React is a declarative and flexible JavaScript library used for building user interfaces and applications. Amongst many other things, it allows you to compose your application UIs from components and offers an accessible route into more complex programming on the front end.
Below you will find a subset of articles from my blog specifically about React. This is an area that I have worked with for many years, and have managed to write about quite a few times. There are forty collected together for you below.

Memoization helps JavaScript functions run faster by caching previous results. Here's a clear guide on how and when to use memoization effectively.

React performance work is often about avoiding repeated effort. This guide looks at memoisation, browser caching, and smarter data‑fetching choices.

React's virtual DOM optimises performance by reducing updates to the real DOM. Here, I explain how it works, how it compares, and why it improves efficiency.

useMemo and useCallbackOptimise React performance with useMemo and useCallback only where profiling shows expensive calculations, unstable functions, or avoidable re‑renders.

Memory leaks in React can cause sluggish performance and excessive memory usage. Here, I explore common causes, how to prevent them, and debugging techniques.

Higher‑Order Components (HOCs) in React wrap components to enhance functionality. Here, I explore how HOCs work, common use cases, and when to use them.

React's reconciliation algorithm updates the UI by comparing the virtual DOM with the previous state. I explore how it works and why it improves performance.

styled‑componentsUse transient props in styled‑components to keep styling‑only props out of the DOM, clean React output, and support safer component migration work.

Add seeded randomisation to an SSR Gatsby project, keeping content order deterministic across builds while still rotating destination‑style content.


useEffect HookUnderstand the empty dependency array in React useEffect, including run‑once behaviour, cleanup, stale data risks, and how different dependencies behave.

A tour of commonly misunderstood JavaScript features, from sort(), slice(), splice(), split(), Math.random(), parseInt(), isNaN(), typeof, and more.

A discussion about the JavaScript modulo operator, its functionality, origins, and diverse applications in web dev, including arithmetic and complex algorithms.

Use Chakra UI breakpoints in React with useBreakpoint and ThemeProvider, including responsive interface choices and custom breakpoint configuration.

Compare React, Vue, and Angular across ecosystem, learning curve, state, templates, team fit, SEO concerns, and how to choose a front‑end framework.

Hiring a React developer is about more than matching keywords. This guide looks at fundamentals, judgement, and what good front‑end signals look like.

Front‑end web development explained through HTML, CSS, JavaScript, UI work, browser behaviour, back‑end integration, and what front‑end developers do.
