Answer: A
The catch
block receives the argument x
. This is not the same x
as the variable when we pass arguments. This variable x
is block-scoped.
Later, we set this block-scoped variable equal to 1
, and set the value of the variable y
. Now, we log the block-scoped variable x
, which is equal to 1
.
Outside of the catch
block, x
is still undefined
, and y
is 2
. When we want to console.log(x)
outside of the catch
block, it returns undefined
, and y
returns 2
.
