NEW QUESTION # 75
Which code statement below correctly persists an objects in local Storage ?
Answer: C
Explanation:
NEW QUESTION # 76
Refer to the following code:
01 let obj = {
02 foo: 1,
03 bar: 2
04 }
05 let output = []
06
07 for (let something of obj) {
08 output.push(something);
09 }
10
11 console.log(output);
What is the value of output on line 11?
Answer: C
Explanation:
The key line is:
for (let something of obj) {
In JavaScript:
* for...of is used to iterate over iterable objects, such as:
* Arrays
* Strings
* Maps
* Sets
* Other objects that implement a [Symbol.iterator] method.
Plain JavaScript objects created with object literal {} are not iterable by default . They do not have [Symbol.
iterator], so using for...of directly on them causes a runtime error.
Specifically:
for (let something of obj) { ... }
will throw a TypeError similar to:
obj is not iterable
Therefore, the loop body never executes, and console.log(output); is never reached without an error.
Why other options are incorrect:
* B. [1, 2]
* To get [1, 2], you could use Object.values(obj) and iterate that array.
* But here, for...of obj never yields values because it throws an error.
* C. [ " foo " , " bar " ]
* To get property names, you could use Object.keys(obj) with for...of.
* Again, the code does not do that; it incorrectly tries to iterate the object directly.
* D. [ " foo:1 " , " bar:2 " ]
* You would need both keys and values, combining them manually.
* The given code does not implement such logic and fails before pushing anything into output.
Hence, the correct answer is:
The answer: A
Study Guide / Concept References (no links):
* Difference between for...of and for...in
* Iterables in JavaScript and [Symbol.iterator]
* Plain objects {} are not iterable by default
* Correct patterns to iterate object keys/values (Object.keys, Object.values, Object.entries)
NEW QUESTION # 77
Code:
01 let array = [1, 2, 3, 4, 4, 5, 4, 4];
02 for (let i = 0; i < array.length; i++) {
03 if (array[i] === 4) {
04 array.splice(i, 1);
05 i--;
06 }
07 }
What is the value of array after execution?
Answer: D
Explanation:
Initial array:
[1, 2, 3, 4, 4, 5, 4, 4]
The loop removes every value equal to 4:
* array.splice(i, 1) removes the element at index i and shifts all later elements left.
* i-- ensures the next index is checked correctly after the shift, preventing skipping elements.
Step-by-step removal:
* Remove the first 4 # array becomes [1,2,3,4,5,4,4]
* Remove next 4 # [1,2,3,5,4,4]
* Remove next 4 # [1,2,3,5,4]
* Remove last 4 # [1,2,3,5]
Final result:
[1,2,3,5]
Option B is correct.
JavaScript Knowledge References (text-only)
* splice(index, deleteCount) removes elements and shifts remaining items.
* Adjusting the loop index when deleting prevents skipping items.
* Arrays update length dynamically after splice().
