Question 1

A developer is writing an EpicScript function to validate user IDs. The user ID must start with 'E' and end with '90'. Given the code snippet below, what will be the final value of the 'isValid' variable?

let userId = "E-SYS-ADMIN-90";
let pattern = "E*90";
let isValid = userId ~= pattern;

Accepted Answer

true

Answer

The EpicScript pattern match operator `~=` checks if a string conforms to a specified pattern. The asterisk `*` acts as a wildcard for zero or more characters. The string "E-SYS-ADMIN-90" starts with 'E' and ends with '90', matching the pattern "E*90". Therefore, the expression evaluates to true.

Question 2

A developer needs to check if a variable, 'patientRecord', has been assigned a value before proceeding. Which of the following is the syntactically correct way to perform this check in EpicScript?

Accepted Answer

if (patientRecord is nil)

Answer

In EpicScript, the correct syntax for checking if a variable is unassigned or explicitly set to `nil` is by using the `is nil` or `is not nil` keywords. Standard equality operators like `==` are used for comparing values, not for `nil` checks.

Question 3

Review the following EpicScript code block. What is the output written to the console?

let score = 75;
let grade = "";
if (score > 90) {
  grade = "A";
} else if (score >= 80) {
  grade = "B";
} else if (score > 70) {
  grade = "C";
} else {
  grade = "D";
}
console.log(grade);

Accepted Answer

C

Answer

The code evaluates the 'score' variable (75) against a series of conditions. The first condition (75 > 90) is false. The second (75 >= 80) is false. The third condition (75 > 70) is true, so the 'grade' variable is assigned the value "C". The script then skips the final 'else' block and prints the value of 'grade', which is "C".

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 logical error is in the line `if (status = "Approved")`. In EpicScript, a single equals sign `=` is the assignment operator, which assigns the value "Approved" to the 'status' variable in each iteration. For comparison, the strict equality operator `==` must be used. The assignment expression itself evaluates to the assigned value ("Approved"), which is a non-empty string and thus treated as true, causing the counter to increment for every item in the array.

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

The correct snippet initializes 'result' to 0. The `loop` runs for i = 0, i = 1, and i = 2. In each iteration, 2 is added to 'result'. The sequence is: result = 0 + 2 (2), then result = 2 + 2 (4), then result = 4 + 2 (6). The final value is 6.
