```javascript
array.setPath$(x, p, v);
// x: a nested array (updated)
// p: path
// v: value
// → x
```

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

var x = [[2, 4], 6, 8];
array.setPath$(x, [1], 60);
// [ [ 2, 4 ], 60, 8 ]

x;
// [ [ 2, 4 ], 60, 8 ]

array.setPath$(x, [0, 1], 40);
// [ [ 2, 40 ], 60, 8 ]

array.setPath$(x, [0, 1, 2], 100);
// [ [ 2, 40 ], 60, 8 ] (path not present, no effect)
