Why is it that array outputs have a () with a number next to it in VS code?
Code:
var Str = 'a string'
console.log(Str)
var Arr = [23, 'Charles']
Arr[0] = 20
console.log(Arr)
var Arr1 = ['Grace', 'Debbie', 'Debby']
Arr1[0] = 'Sophie'
console.log(Arr1)Output:
a string
(2) [20, 'Charles']
(3) ['Sophie', 'Debbie', 'Debby']

It is just the elements count. BTW, console.log() of any object (an array is also an object) is parsed in that way.
