Article Introduction：Reasons for more efficient processing of data with Stream include memory savings, performance improvements, and support for asynchronous processing. 1. Save memory: avoid loading all data at once through blocking processing; 2. Improve performance: handle read and write operations in parallel; 3. Support asynchronous processing: suitable for non-blocking I/O operations. In the example, the file is read block by block through the Readable stream, and the Writable stream is written to the target file after being converted by the Transform stream. The entire process is low in memory and high in efficiency. In practical applications, attention should be paid to backpressure control, error handling and chain calls of multi-converting streams to ensure stable and efficient stream processing.

Article Introduction：In IoT systems, the key links in data aggregation and processing include data aggregation, edge computing and data cleaning. ① Data aggregation reduces redundant data through timed batch uploads, event triggering or statistical summary; ② Edge computing is initially processed near the device side to reduce delays and improve fault tolerance; ③ Data cleaning removes outliers, completes missing fields and unifies the format, laying the foundation for subsequent analysis. In addition, it is recommended to use message queues to buffer data, adopt a hierarchical processing structure, strengthen monitoring and pre-security mechanisms during deployment to build an efficient and stable data pipeline.

Article Introduction：Geospatial data processing is a technology that ordinary people can master. Its core lies in understanding five steps: first, clarify the data source and format, such as Shapefile, GeoJSON, KML, GPX and PostGIS; second, carry out data cleaning and pre-processing, including deduplication, unified projection, complementary attributes and checking coordinate validity; third, analyze and visualize based on business needs, such as heat map, buffer analysis, distance calculation and cluster analysis; fourth, select appropriate output formats for display or sharing, such as GeoJSON, PDF, PNG, Shapefile or CSV; fifth, attach data descriptions to ensure that others can correctly understand and use them. As long as you master these key points and practice them manually, you can be effective

Article Introduction：WebStreamsAPI is a standard interface for efficient processing of streaming data. It mainly includes three stream types: ReadableStream, WritableStream and TransformStream. It is suitable for large file uploads, real-time audio and video processing and other scenarios. The advantage is that it can process data in chunks, reduce memory usage and improve response speed. When using it, streaming operations are usually combined with FetchAPI or file reading, such as parsing JSON while downloading, or uploading files while reading. Practical applications include file upload optimization, data analysis speedup and real-time audio and video processing. Notes include checking browser compatibility, improving error handling, reasonable control of back pressure and timely shutting down flow to avoid resource leakage

Article Introduction：WebWorkers are suitable for handling time-consuming tasks to avoid blocking the main thread. The steps to create a WebWorker include: 1. Prepare the worker.js file; 2. Create an instance through newWorker() in the main thread; 3. Use postMessage() to send messages; 4. Receive results through onmessage; 5. Call terminate() when not in use. Suitable tasks include a large number of mathematical operations, timing tasks, data preloading and processing, and long-running tasks. Notes include: communication overhead is high, TransferableObjects should be used; DOM and some global variables cannot be accessed; debugging is more troublesome; multiple works should not be abused

Article Introduction：Use flatMap and groupingBy to implement classification summary of nested collections; 2. Use Stream.iterate and takeWhile to implement state-based stream processing; 3. Use partitioningBy to cooperate with downstream collectors for grouping statistics; 4. Use Stream.concat to merge multiple streams and deduplicate them through toMap and control conflict resolution; 5. Use custom unchecked function wrapper to safely handle detected exceptions in the stream; 6. Use merge functions in toMap to elegantly handle key conflicts; 7. Use parallelStream with caution, only enabled when the data is large and the operation is CPU-intensive, and ensure that the operation is stateless
