eplaced an inefficient forEach loop with the find() method in the
render()
function's container lookup logic, enabling early exit when a matching container is found.
Type of Change
Bug fix (performance optimization)
New feature
Breaking change
Documentation update
The Problem
In
src/pure.js
lines 286-293, when reusing an existing container, the code used forEach to search through mountedRootEntries:
javascript
mountedRootEntries.forEach(rootEntry => {
if (rootEntry.container === container) {
root = rootEntry.root
}
})
The forEach method continues iterating through all entries even after finding the matching container. This is inefficient because:
It performs unnecessary iterations after the match is found
Performance degrades as more containers are mounted
The code doesn't communicate the intent to find a single entry
The Solution
Replaced forEach with the find() method which stops iteration immediately upon finding a match:
javascript
const rootEntry = mountedRootEntries.find(
rootEntry => rootEntry.container === container,
)
if (rootEntry) {
root = rootEntry.root
}
This change:
⚡ Stops searching immediately when a match is found (early exit optimization)
📈 Improves performance, especially with multiple mounted containers
🎯 Makes the code intent clearer - we're looking for one specific entry
✅ Uses a more idiomatic JavaScript pattern
