A clearer way to read JavaScript

Keep the detail. See the structure.

Use this workspace to inspect functions, objects, expressions and control flow. Paste your source, choose format, and follow the resulting structure. The sample button supplies a starting point only when you request it.

Example JavaScript input

const orders=[{price:12,quantity:2},{price:8,quantity:3}];function total(items){return items.reduce((sum,item)=>sum+item.price*item.quantity,0);}console.log(total(orders));

This page also accepts supported mixed web source. You can use the Web workspace for documents combining several supported languages. A complete page is not required.

Formatting helps with reading and structural review. It does not replace the language compiler, database validation or testing of application behavior.

Before you begin

What should I paste here?

Paste JavaScript source you want to study, especially functions, objects, expressions and control flow. Your input starts empty; loading a sample is optional.

Does formatting execute my code?

Formatting does not execute submitted SQL or application code. The separate Web page preview can run browser-side content in an isolated frame after you choose to open it.

How is my code handled?

The hosted site processes formatting on its server. Formatting activity stores the exact submitted source and its outcome. Direct local-file training works without activity requests. See our privacy information before submitting sensitive code.
