assert.doesNotMatch()

Priya only reaches for assert.doesNotMatch() (function) when Priya walking through assert.doesNotMatch function has to stay correct in a first job task.

Keep assert.doesNotMatch() (function) small. Priya should finish Priya walking through assert.doesNotMatch function in a few lines, not a 40-line dump.

Skip assert.doesNotMatch() (function) and copy-pasting assert.doesNotMatch function without a dry-run shows up in a first job task.

Use assert.doesNotMatch() (function) when Priya walking through assert.doesNotMatch function must stay clear. If a simpler Node.js step works, use that instead.

assert.doesNotMatch() (function) trap: copy-pasting assert.doesNotMatch function without a dry-run. Priya loses marks for that every viva.

After assert.doesNotMatch() (function), Priya should still remember copy-pasting assert.doesNotMatch function without a dry-run.

Close assert.doesNotMatch() (function) with: “If I skip it, Priya walking through assert.doesNotMatch function goes wrong like this: copy-pasting assert.doesNotMatch function without a dry-run.”

Exam tip

Board: Priya walking through assert.doesNotMatch function. Dry-run assert.doesNotMatch() (function). Name the trap: copy-pasting assert.doesNotMatch function without a dry-run.

Example

// assert.doesNotMatch()
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

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

assert.doesNotMatch(): find user 2, then list names. Say both prints.

Ruleassert.doesNotMatch() (function) → one assert.doesNotMatch function step Priya can write from memory.
