JSON Formatter

Reading API responses, parsing AWS Lambda logs, wrangling manifests — same job over and over. This lab pulls formatted output and an interactive tree from a single input.

{
  "name": "Yiğit Yalım",
  "role": "Software Engineer",
  "skills": [
    "TypeScript",
    "Next.js",
    "Rust"
  ],
  "active": true,
  "projects": 12,
  "address": null
}

In practice

• Indent (2sp / 4sp / tab) — match your repo style
• Minify — JSON.stringify(value) to one line for network payloads
• Collapsible tree — walk deep JSON visually, lazy reveal
• Error position — Unexpected token } in JSON at position 42 becomes a line/column highlight

V8 (Chrome/Node) returns "position N", SpiderMonkey (Firefox) returns "line X column Y" — the lab parses both formats.
