function default.equal
Usage in Deno
```typescript import mod from "node:node__assert.d.ts"; ```
equal(actual: unknown,expected: unknown,message?: string | Error,): void
**Strict assertion mode**
An alias of [strictEqual](../.././node__assert.d.ts/~/default.strictEqual).
**Legacy assertion mode**
> Stability: 3 - Legacy: Use [strictEqual](../.././node__assert.d.ts/~/default.strictEqual) instead.
Tests shallow, coercive equality between the `actual` and `expected` parameters
using the [`==` operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Equality). `NaN` is specially handled
and treated as being identical if both sides are `NaN`.
```js
import assert from 'node:assert';
assert.equal(1, 1);
// OK, 1 == 1
assert.equal(1, '1');
// OK, 1 == '1'
assert.equal(NaN, NaN);
// OK
assert.equal(1, 2);
// AssertionError: 1 == 2
assert.equal({ a: { b: 1 } }, { a: { b: 1 } });
// AssertionError: { a: { b: 1 } } == { a: { b: 1 } }
```
If the values are not 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`.
