JavaScript Statements Mocktest

The code snippet uses a while loop to print even numbers from 10 to 0. It starts with x being 10 and prints the value of x to the console in each iteration, then decrements x by 2. This process continues until x becomes 0, at which point the loop stops. Therefore, the output will be: 10 8 6 4 2 0

The code snippet uses a for loop to iterate through all elements of the array numbers and prints each element to the console. It starts with i being 0 and iterates until i is less than the length of the array (numbers.length). In each iteration, it accesses the element at index i using numbers[i] and logs it to the console. Therefore, the output will be: 1 2 3 4 5

The continue; statement is used to skip the current iteration in a loop and continue to the next iteration. When encountered, it immediately stops the current iteration and jumps to the next iteration in the loop block.

The code snippet uses a for...of loop to iterate through each element n in the array nums. Inside the loop, it checks if n is even (divisible by 2), and if so, it prints n to the console. Therefore, the output will be: 2 4

The statement uses nested ternary conditional operators (? :) to assign different values to result based on the value of x. If x is greater than 0, it assigns "Positive" to result. If x is less than 0, it assigns "Negative" to result. Otherwise, it assigns "Zero" to result. This allows for conditional assignment of values based on multiple conditions in a single statement.

The code snippet uses a for loop to iterate from 0 to 2 (inclusive) and prints the value of i to the console in each iteration. The loop is initialized without declaring i in the initialization part of the loop. Therefore, i starts with its previously declared value, which is 0 in this case. The output will be: 0 1 2

The code snippet uses a while loop to print numbers from 5 to 0. It starts with x being 5 and prints the value of x to the console in each iteration, then decrements x by 1. This process continues until x becomes 0, at which point the loop stops. Therefore, the output will be: 5 4 3 2 1 0

The return result; statement is used inside a function to exit the function and return a value. When encountered, it exits the current function's execution and passes the value of result (or any other variable or expression) back to the caller of the function. This allows functions to produce output values that can be used in other parts of the program.

The code snippet uses a do...while loop to print numbers from 3 to 1. It starts with i being 3 and prints the value of i to the console in each iteration, then decrements i by 1. This process continues until i is no longer greater than 0, at which point the loop stops. Therefore, the output will be: 3 2 1

The output will be "Even" because the condition x % 2 === 0 checks if x is divisible by 2 without a remainder, which is true for the value 10. Therefore, the code inside the if block executes, printing "Even" to the console.
