This code snippet writes a string to disk at a particular absolute path. It uses the fast Bun.write() API to efficiently write data to disk. The first argument is a destination; the second is the data to write. 
const path = '/path/to/file.txt';
await Bun.write(path, 'Lorem ipsum');
Any relative paths will be resolved relative to the project root (the nearest directory containing a package.json file). 
const path = './file.txt';
await Bun.write(path, 'Lorem ipsum');
You can pass a BunFile as the destination. Bun.write() will write the data to its associated path. 
const path = Bun.file('./file.txt');
await Bun.write(path, 'Lorem ipsum');
Bun.write() returns the number of bytes written to disk. 
const path = './file.txt';
const bytes = await Bun.write(path, 'Lorem ipsum');
// => 11
