const nested = { a: { b: { c: { d: "deep" } } } };
console.log(nested);
// Default (depth 2): { a: { b: [Object] } }
// With depth 4: { a: { b: { c: { d: 'deep' } } } }
The CLI flag takes precedence over the configuration file setting.
Reading from stdin
In Bun, the console object can be used as an AsyncIterable to sequentially read lines from process.stdin.
adder.tsfor await (const line of console) {
console.log(line);
}
This is useful for implementing interactive programs, like the following addition calculator.
adder.tsconsole.log(`Let's add some numbers!`);
console.write(`Count: 0\n> `);
let count = 0;
for await (const line of console) {
count += Number(line);
console.write(`Count: ${count}\n> `);
}
To run the file:
terminalbun adder.ts Let's add some numbers! Count: 0 > 5 Count: 5 > 5 Count: 10 > 5 Count: 15
