NEW QUESTION # 12
01 function changeValue(obj) {
02 obj.value = obj.value / 2;
03 }
04 const objA = { value: 10 };
05 const objB = objA;
06
07 changeValue(objB);
08 const result = objA.value;
What is the value of result?
Answer: A
Explanation:
objA is created with:
{ value: 10 }
objB = objA;
Objects in JavaScript are assigned by reference, not copied.
So objA and objB refer to the same object in memory.
The function:
changeValue(obj) {
obj.value = obj.value / 2;
}
When called as changeValue(objB), it updates the value property of the shared object:
value = 10 / 2 → 5
Therefore:
objA.value === 5
Because objA and objB refer to the same object, the change is reflected in both.
JavaScript Knowledge Reference (text-only)
Objects are stored and passed by reference.
Mutating an object inside a function mutates the original object.
NEW QUESTION # 13
Refer to the code:
const pi = 3.1415926;
What is the data type of pi?
Answer: A
Explanation:
JavaScript has one numeric data type for all real numbers, whether integers or decimals.
This type is simply called:
Number
It follows the IEEE 754 double-precision floating-point standard internally, but JavaScript does not expose separate types like float, double, or decimal.
Therefore:
It is not Float → JavaScript does not have float primitives.
It is not Double → this refers to the underlying IEEE 754 representation, but JavaScript's type is still just "Number." It is not Decimal → JavaScript has no built-in decimal type.
The correct answer is Number.
JavaScript Knowledge Reference (text-only)
JavaScript has a single numeric type: Number.
All numbers-integers, fractions, floating point-use the Number type.
NEW QUESTION # 14
Which statement accurately describes the behavior of the async/await keywords?
Answer: C
Explanation:
When async is added to a function:
async function example() {}
JavaScript guarantees:
The function always returns a Promise, regardless of what is returned inside.
Inside the function, await pauses execution until a Promise resolves.
Code appears synchronous even though it uses asynchronous behavior.
Analysis of each option:
A incorrect:
Not "sometimes"-an async function always returns a Promise.
B incorrect:
Async functions can be called just like normal functions.
C incorrect:
Async/await has nothing to do with classes specifically.
D correct:
This is the standard description:
"Async functions behave asynchronously but allow writing code that looks synchronous." JavaScript Knowledge Reference (text-only) async functions always return Promises.
await pauses execution of the async function.
Async/await syntax creates synchronous-looking code on top of asynchronous operations.
NEW QUESTION # 15
A developer creates a new web server that uses Node.js. It imports a server library that uses events and callbacks for handling server functionality. The server library is imported with require and is made available to the code by a variable named server. The developer wants to log any issues that the server has while booting up.
Which code logs an error at boot time with an event?
Answer: B
Explanation:
Event-driven Node-style APIs expose events via .on(eventName, handler).
To listen for error events:
server.on('error', (error) => {
console.log('ERROR', error);
});
A and B assume methods .error or .catch that don't exist on typical event emitters.
C only catches synchronous errors from server.start(), not async event-based errors.
NEW QUESTION # 16
Refer to code below:
Let productSKU = '8675309' ;
A developer has a requirement to generate SKU numbers that are always 19 characters lon, starting with 'sku', and padded with zeros.
Which statement assigns the values sku0000000008675309 ?
Answer: B
