array.isEqual(x, y, [fc], [fm]);
// x:  an array
// y:  another array
// fc: compare function (a, b)
// fm: map function (v, i, x)
```

```javascript
const array = require("extra-array");

var x = [1, 2];
array.isEqual(x, [1, 2]);
// true

array.isEqual(x, [11, 12]);
// false

array.isEqual(x, [11, 12], (a, b) => (a % 10) - (b % 10));
// true

array.isEqual(x, [11, 12], null, v => v % 10);
// true
