JavaScript Input

function buildReport(items){const active=items.filter((item)=>item.active);return active.map((item)=>({id:item.id,label:`${item.name} (${item.region})`,tags:item.tags??[]}));}

const summary=buildReport([{id:1,name:"Ada",region:"APAC",active:true,tags:["ops","release"]},{id:2,name:"Linus",region:"EU",active:false}]);

console.log(summary);

    id: item.id,
    label: `${item.name} (${item.region})`,
    tags: item.tags ?? []
  }));
}

const summary = buildReport([{

FAQ

Does this pretty print javascript route run entirely in browser?

Yes. The formatter runs in browser so pasted code or styles stay local while you review and copy the result.

Does this route return copy-ready pretty printed javascript?

Yes. After formatting, the result stays in the shared output workspace so you can inspect and copy it immediately.
