   This is not a valid bug report. Please give details about what you think the problem is. I don't see an issue with the example code you gave.

   The code block I gave is the corrected one.
   The original example:

   const sqlPromise = initSqlJs({
     locateFile: file => `https://path/to/your/dist/folder/dist/${file}`
   });
   const dataPromise = fetch("/path/to/database.sqlite").then(res => res.arrayBuffer());
   const [SQL, buf] = await Promise.all([sqlPromise, dataPromise])
   const db = new SQL.Database(new Uint8Array(buf));

   will raise an error as SyntaxError: await is only valid in async functions, async generators and modules as shown in MDN.

   That's why I recomment to update the example for fetch in browser.

   Oh, I get what you are saying. It seemed evident to me that the given example had to be run in an async context (which is now supported at the root level in many places, including node). If you want to add a note to specify that (without changing the code snippet), I'll accept a pull request :)
