Node.js: What is the difference between process.nextTick() and setImmediate()?

nextTick — before event loop. setImmediate — in event loop.

1process.nextTick(() => console.log("nextTick"));
2setImmediate(() => console.log("immediate"));

• nextTick — higher priority.
• setImmediate — lower priority.
• nextTick — can block event loop.
