- Rewrite the following JavaScript code using jQuery, to hide button2 and button3 once button1 is clicked.The acclaimed _NumPy_ library, that `Simpy` is inspired by, allows you to use the subscription operator not just to select individual items, but also to filter with a mask. It adds a second usage to the operator, just like you have had two uses of many of the operators above, such as adding two `Simpy`s or a `Simpy` and a `float`. The big idea of the second usage of subscription notation is that if instead of giving an `int` inside the subscription brackets you give a `list[bool]`, the expression will return a new `Simpy` object containing only the _masked_, or filtered, `values`. For example: ~~~python a = Simpy([1.0, 2.0, 3.0, 4.0, 2.0, 1.0]) mask = a > 2.0 print(mask) # Output: [False, False, True, True, False, False] b = a[mask] print(b) # Output: Simpy([3.0, 4.0]) ~~~ The above example did not need to establish a separate variable named `mask`, it only did so to make it obvious what the `mask` values were. More conventionally, the above example would be written in a…rite a client that generates arrays of items of varioustypes with random key values, including the following:■ String key (at least ten characters), one double value■ double key, ten String values (all at least ten characters)■ int key, one int[20] value
