HOW WE MADE OUR RICH TEXT EDITOR LOAD FASTER

Summary from the TLDR Web Dev newsletter

CKEditor 5 initially struggled with performance issues when loading large, complex documents due to its multi-layered architecture. To fix these issues, its team reduced redundant conversions, improved tree traversal, and batched operations. As a result, document load times were reduced by 6–7x, showing the power of improving underlying algorithms within code rather than focusing on JavaScript micro-optimizations first.
