A Zed editor extension that provides syntax highlighting for JSON Lines (JSONL) and Newline Delimited JSON (NDJSON) files.
JSON Lines is a format for storing structured data with one JSON object per line. Each line is a valid JSON value, making it suitable for streaming and processing large datasets.

{"name": "Bob", "age": 35}- Syntax highlighting for
.jsonland.ndjsonfiles - Automatic file detection
