High-Performance Web-Based Code Editor

High-Performance Web-Based Code Editor

Design a browser-based code editor similar to VS Code. The system must support opening large files (100k+ lines) without UI lag, provide syntax highlighting, and manage a complex layout with sidebars and tabs. Focus specifically on the rendering strategy for the text area, the data structures used to manage text edits efficiently, and how to offload heavy computations to ensure a smooth 60fps typing experience. Address the trade-offs between DOM-based and Canvas-based rendering, and how to handle file system persistence in a browser environment.
