Question 4

A junior developer has written the following loop to count all approved orders. However, the final count is incorrect. What is the logical error in this EpicScript code?

let approvedCount = 0;
let orderStatus = ["Approved", "Pending", "Approved", "Shipped"];
forEach (status in orderStatus) {
  if (status = "Approved") {
    approvedCount++;
  }
}
console.log(approvedCount);

Accepted Answer

The `if` statement is using the assignment operator `=` instead of the equality operator `==`.

Answer

The `forEach` loop syntax is incorrect for iterating through an `Arr`.

Answer

The `approvedCount` variable was not initialized correctly.

Answer

The string "Approved" is case-sensitive and will not match.

Question 5

Which of the following EpicScript code snippets will result in the variable 'result' having a final value of 6?

Accepted Answer

let result = 0;
loop (let i = 0; i < 3; i++) {
  result = result + 2;
}

Answer

let result = 0;
let nums = [1, 2, 3, 4];
forEach (n in nums) {
  if (n > 2) {
    result = result + n;
  }
}

Answer

let result = 10;
if (result < 5 && result > 0) {
  result = 6;
} else {
  result = 5;
}

Answer

let result = 1;
loop (let i = 1; i <= 3; i++) {
  result = result * i;
}

let adjustments = [-10, 5, "SKIP", 15];
forEach (adj in adjustments) {
  if (typeof(adj) == "Num") {
    baseValue = baseValue + adj;
  } else {
    continue;
  }
}
