Managing binary data, files, and browser memory.

Why this section exists?

Handling files is more than just using an <input type="file">. As a Front-end Engineer, you must manage how data is processed to avoid browser crashes and memory leaks.

The Core Problem

Large files (like medical videos or high-res images) can freeze the UI or fail mid-way due to memory limits.

Engineering Patterns:

  • Memory Management: Learning when to release resources (Revoke Object URLs).
  • Data Partitioning: Breaking large files into manageable chunks.
  • Integrity: Ensuring the file is safe and complete before it reaches the server.

Impact: This ensures the application remains fast and stable, even when processing gigabytes of data.
