Solve React "Too many re-renders"
Stop infinite execution loops in React hooks. Learn why functions executing inside render threads crash your browser viewport.
Quick React Scope Solution
Pass status update functions as inline callback functions, likeonClick={() => setS(v)}, to resolve infinite state re-rendering errors.
# The Infinite Re-render Loop
In React, the following construct executes during rendering, updating state immediately, triggering another rebuild, and crashing the call stack:
``javascript
// This executes state changes immediately on render
<button onClick={setCount(count + 1)}>Click</button>
`
# Step 1: Wrap Inside Anonymous Callbacks
To solve this issue, wrap the state update inside a callback reference. This guarantees the action is only executed upon click:
`javascript
// Wrapped within an arrow callback function
<button onClick={() => setCount(count + 1)}>Click</button>
`
# Step 2: Correct Hooks Dependencies
Ensure state triggers within useEffect are gated using correct dependency guidelines. Never set a state value inside a useEffect hook if it is also listed in his own dependency list, as this triggers infinite cycles:
`javascript
// WRONG: Triggers update cycle infinitely
useEffect(() => {
setCount(count + 1);
}, [count]);
// CORRECT: Utilize state modifiers or primitive dependency guards
useEffect(() => {
document.title = Count is ${count};
}, [count]);
