 # JSON.parseBinary
+The JSON.parseBinary proposal introduces a new static method to the global JSON object. It allows developers to parse JSON directly from binary data (Uint8Array, ArrayBuffer) without first converting it into a JavaScript string. Unlike the traditional JSON.parse, this method returns a **result object** instead of throwing an exception, significantly improving performance and memory efficiency in high-load environments like HTTP servers.
+## The Core Problems
 
+The current workflow for parsing network data in JavaScript is:
+```
+Network Bytes → TextDecoder.decode() (String) → JSON.parse(String) → Object
+```
 
+This pipeline suffers from three major "hidden" costs:
+
+    - The Intermediate String Penalty: Converting binary data to a string creates a massive temporary copy in memory. If a single multi-byte character (like an emoji) is present, V8 may upgrade the entire string to UTF-16, doubling its memory footprint. This increases Garbage Collection (GC) pressure and can lead to "stop-the-world" pauses.
+
+    - The SyntaxError Overhead: JSON.parse is "throw-heavy." When it encounters invalid JSON, it generates a SyntaxError with a full stack trace. Benchmarks show that creating and throwing an Error is roughly 500x more expensive than returning a plain object. In network scenarios, invalid payloads are common and shouldn't require the overhead of a debugging stack trace.
+
+    - Memory Pollution: Current methods often leave the original binary buffer and the intermediate string in memory longer than necessary, causing the heap to swell and slowing down the entire system.
+
+## Proposed Solution: `JSON.parseBinary`
+
+The proposal suggests a synchronous, single-pass parser with the following TypeScript signature:
+TypeScript
+```typescript
+JSON.parseBinary(input: ArrayBufferLike | Uint8Array): 
+  { ok: true; value: any } | 
+  { ok: false; message: string };
+```
+
+How the Pipeline Changes:
+## Key Advantages
+|Feature|JSON.parse|JSON.parseBinary|
+|---|---|---|
+|Memory|Allocates 2x-3x payload size for strings|Zero intermediate string allocation|
+|Error Handling|Uses try-catch (slow, blocks inlining)|Returns a result object (fast, ergonomic)|
+|Performance|Significant GC overhead and stack trace costs|Optimized for "untrusted" network input|
+|Simplicity|Requires TextDecoder and global pollution|Clean, self-contained API|
+
+    - Early Abort: If the first byte is invalid, JSON.parseBinary returns immediately without wasting any time decoding the rest of the buffer.
+
+    - Selective Encoding: It only creates strings for the actual keys and values it extracts, keeping the rest of the data in its compact binary form during the walk.
+
+    - Developer Experience: Eliminates nested try-catch blocks, allowing for cleaner code when handling potentially malformed API responses.
+
+## Synergy with ArrayBuffer.prototype.detach()
+
+This proposal is designed to work alongside the detach() proposal. Together, they allow a server to:
+
+    - Receive a binary chunk.
+
+    - Parse it directly into an object.
+
+    - Manually release the binary memory immediately after parsing, ensuring the memory footprint never stays higher than necessary.
