質問 # 115
Refer to the code below:
Async funct on functionUnderTest(isOK) {
If (isOK) return 'OK';
Throw new Error('not OK');
)
Which assertion accurately tests the above code?
正解：A
質問 # 116
Refer to the following array:
let arr = [1, 2, 3, 4, 5];
Which two lines of code result in a second array, arr2, created such that arr2 is a reference to arr?
正解：C、D
解説：
The correct answers are C and D.
Arrays in JavaScript are objects. When an array variable is assigned directly to another variable, both variables point to the same array in memory.
Option C is correct:
let arr2 = arr;
This does not create a new array. It creates another reference to the same array.
Example:
arr2.push(6);
console.log(arr);
Output:
[1, 2, 3, 4, 5, 6]
Changing arr2 also affects arr because both variables reference the same array.
Option D is also correct:
let arr2 = arr.sort();
The sort() method sorts the array in place and returns the same array reference. Therefore, arr2 refers to the same array object as arr.
The incorrect options create copies:
let arr2 = arr.slice(0, 5);
creates a shallow copy.
let arr2 = Array.from(arr);
also creates a new shallow copy.
So the two lines that make arr2 reference the original arr are C and D.
質問 # 117
GIven a value, which three options can a developer use to detect if thevalue is NaN?
Choose 3 answers !
正解：B、C
質問 # 118
A developer is trying to handle an error within a function.
Which code segment shows the correct approach to handle an error without propagating it elsewhere?
正解：C
質問 # 119
Given the following code:
let x = ('15' + 10) * 2;
What is the value of x?
正解：D
解説：
Comprehensive and Detailed
Evaluate step by step:
'15' + 10
+ with a string operand performs string concatenation.
10 is coerced to '10'.
Result: '1510'.
'1510' * 2
* always performs numeric multiplication.
'1510' is converted to the number 1510.
1510 * 2 = 3020.
So x is 3020.
