Question

Guess the value stored in the "rowHeight" variable value of the following code:
let height = 40
let isCheck = true
let rowHeight = height + (isCheck ? 50 : 20)
Can anyone help me?

Answer 1

Value stored in rowHeight will be 90.
This is because isCheck is true so the value after ? will be considered that is 50.
rowHeight= 40+50=90

Answer 2

The value for the rowheight will be 90 because let height=40
let rowheight =height(is check?50:20)
therefore rowheight=40+50=90
