Blob API
The Blob API is a web API in JavaScript that provides an interface for handling raw binary data, known as blobs (Binary Large Objects). It allows developers to create, manipulate, and store data such as images, videos, or files directly in the browser. This API is commonly used for file uploads, in-memory data processing, and working with large datasets without server-side interaction.
Developers should learn the Blob API when building web applications that require client-side file handling, such as image editors, video processing tools, or document upload features. It is essential for scenarios where you need to slice, combine, or stream binary data efficiently, enabling offline capabilities and reducing server load by processing data locally in the browser.
