the console shows undefined for the following loop. the issue is in array[i]
as it says i is undefined but it is the index for the loop elements. I don’t want to change the x to I as I want to run the code only once and test that it will stop as x is not < 5.
let x = 5; let i; let array = ["x", "y", "z"]; do { console.log(array[i]); //statement i++; //increment } while (x < 5); //condition

Answer
so the problem with your code is that you initialised i without difining it let i;
and then you are incrementing it i++
,
set let i = 0;
let x = 5; let i = 0; let array = ["x", "y", "z"]; do { console.log(array[i]); //statement i++; //increment } while (x < 5); //condition
now if x is not less than 5 then the loop will run once
but there will be a problem that if x is less than 5 then loop will run infinitely so instead of just x < 5
dot x < 5 && i < array.length
let x = 4; let i = 0; let array = ["x", "y", "z"]; do { console.log(array[i]); //statement i++; //increment } while (x < 5 && i < array.length); //condition
now it will work just fine !
