assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function in Node.js

assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function is a Node.js topic. In plain words you use it for a short assert.failactual, expected[, message[, operator[, stackStartFn]]] function example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest assert.failactual, expected[, message[, operator[, stackStartFn]]] function example you can type. Type it, run it, and say what you see. If you can do that from memory, you know assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function.

From the example next to this theory: assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function in Node.js: find user 2, then list names. Say both prints..

Trap: only saying “assert.failactual, expected[, message[, operator[, stackStartFn]]] function” with no example. Fix that before you talk about advanced Node.js.

Viva: what is assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function? Then show the smallest assert.failactual, expected[, message[, operator[, stackStartFn]]] function example you can type. Then name the trap.

What is assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function? Show this: the smallest assert.failactual, expected[, message[, operator[, stackStartFn]]] function example you can type. Trap: only saying “assert.failactual, expected[, message[, operator[, stackStartFn]]] function” with no example.

Example

// assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function in Node.js
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },

}

console.log(findUser(2));
console.log(users.map((u) => u.name));

assert.fail(actual, expected[, message[, operator[, stackStartFn]]]) function in Node.js: find user 2, then list names. Say both prints.
