x is declared as 0.
Do while loop is stated with incrementing x value as x++ and the same is sent for output to console with the line of code “console.log("The value of x is : "+x);".
Finally the while part checks the condition as x is not equal to 5 as while (x!=5);a block of code for one time and check the condition.

Executing the do while loop in the nodejs framework produces the output of the variable x.
