What steps will reproduce the bug?

code:
Array.prototype[1] = 2
console.log(Array.prototype);

result:

How often does it reproduce? Is there a required condition?

When I knew that Array.prototype was an Array, I tried to assign a value to Array.prototype[x].
Assigning only Array.prototype[1] results in an error that will occur when reading Array.prototype.

What is the expected behavior? Why is that the expected behavior?

In Chrome, you will get the following results：

Array.prototype[1] = 2
console.log(Array.prototype);

result:
[1: 2, at: ƒ, concat: ƒ, copyWithin: ƒ, fill: ƒ, find: ƒ, …]

What do you see instead?

code:
Array.prototype[1] = 2
console.log(Array.prototype);

result:
Object(2) [ <1 empty item>, 2 ]
node:internal/process/task_queues:77
callback();
