proxy logging in JavaScript

JavaScriptProxylogging proxyadvanced

What this snippet does

A logging Proxy is transparent to the rest of the code — no changes needed to the consumer, yet every access is recorded.

Expected output

[store] GET count
[store] SET count = 5
[store] GET count

Why practise typing this

Typing proxy code builds muscle memory for the symbols and indentation JavaScript uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
