method Console.assert
Usage in Deno
```typescript import { type Console } from "node:node__console.d.ts"; ```
Console.assert(value: any,message?: string,...optionalParams: any[],): void
`console.assert()` writes a message if `value` is [falsy](https://developer.mozilla.org/en-US/docs/Glossary/Falsy) or omitted. It only
writes a message and does not otherwise affect execution. The output always
starts with `"Assertion failed"`. If provided, `message` is formatted using
[`util.format()`](https://nodejs.org/docs/latest-v22.x/api/util.html#utilformatformat-args).
If `value` is [truthy](https://developer.mozilla.org/en-US/docs/Glossary/Truthy), nothing happens.
```js
console.assert(true, 'does nothing');
console.assert(false, 'Whoops %s work', 'didn\'t');
// Assertion failed: Whoops didn't work
console.assert();
// Assertion failed
```
