Junior Dev's Dream vs. The useEffect Nightmare
Description
A two-part meme contrasting the expectations of new developers with the harsh reality of professional codebases. The top text, under 'New developers:', reads, 'I can't wait to work on a real, professional codebase and leave my spaghetti code behind!'. Below this, under 'The codebase:', is a screenshot of a post from the r/reactjs subreddit titled, 'How to cope with a fragile React codebase'. The post, flaired as 'Needs Help', describes a project of ~60K lines of code with around 650 `useEffect` calls, many of which trigger cyclical state updates that create an unstable, fragile system. The technical humor lies in the irony: the 'professional' codebase is a far more complex and terrifying version of spaghetti code than anything a junior developer might write. It highlights the pain of inheriting massive technical debt, specifically the misuse of React's `useEffect` hook, which can lead to unpredictable side effects and a nightmare debugging experience for even senior engineers

A junior developer's spaghetti code is like a tangled ball of yarn. A senior's fragile `useEffect` codebase is a distributed yarn-demolition service that only fails on Tuesdays
60 K LOC and 650 useEffects - at that point it’s not a React app, it’s a client-side distributed system with zero observability budget
After 20 years in this industry, I've learned that 'professional codebase' is just what we call the spaghetti that survived production long enough to accumulate 650 useEffects - each one a monument to a developer who said 'I'll refactor this later' before their two-week notice
Ah yes, the classic React codebase where 650 useEffect hooks form a distributed consensus algorithm that would make Paxos jealous - except instead of achieving fault tolerance, they've achieved a delicate equilibrium where nobody dares touch anything because the entire state machine might collapse into a render loop singularity. Welcome to production, where 'professional codebase' means the spaghetti has been carefully organized into lasagna layers of cascading side effects
650 useEffect hooks later, your SPA isn’t a UI - it’s an eventually consistent system that forgot to implement a topological sort
650 useEffects in 60K LOC? That's not a codebase, it's a stateful Rube Goldberg machine where one render regrets birth the next
Enterprise React: 60k LOC and 650 useEffect hooks. It’s not spaghetti; it’s a cyclic dependency graph that occasionally converges to a UI - our CTO calls it “eventual consistency.”

I've seen incredible fuck ups in a number of languages You can screw up everything, if you are stupid enough Comment deleted

that's just terrible code architecture, nothing else Comment deleted
You can do this in any language that has watchers and a global state. Add a watcher to a variable and update very same variable on change. It's not even about js. Comment deleted
Nothing unusual, it's just that they decided to build the system around effectual consistency Comment deleted
