function default.notEqual
Usage in Deno
```typescript import mod from "node:node__assert.d.ts"; ```
notEqual(actual: unknown,expected: unknown,message?: string | Error,): void
**Strict assertion mode**
An alias of [notStrictEqual](../.././node__assert.d.ts/~/default.notStrictEqual).
**Legacy assertion mode**
> Stability: 3 - Legacy: Use [notStrictEqual](../.././node__assert.d.ts/~/default.notStrictEqual) instead.
Tests shallow, coercive inequality with the [`!=` operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Inequality). `NaN` is
specially handled and treated as being identical if both sides are `NaN`.
```js
import assert from 'node:assert';
assert.notEqual(1, 2);
// OK
assert.notEqual(1, 1);
// AssertionError: 1 != 1
assert.notEqual(1, '1');
// AssertionError: 1 != '1'
```
If the values are equal, an `AssertionError` is thrown with a `message` property set equal to the value of the `message` parameter. If the `message` parameter is undefined, a default error
message is assigned. If the `message` parameter is an instance of an `Error` then it will be thrown instead of the `AssertionError`.
