a. True
b. False

Answer 1

To create a script that converts length in centimeters to another unit using the switch-case method in JavaScript, you can prompt the user for the length and unit, and then perform the conversion based on the user's choice using a switch-case statement. The result can be displayed using the alert function.

Step-by-step explanation:

Using the switch-case method in JavaScript

Here is an example of how you can create a script using the switch-case method in JavaScript to convert a length in centimeters to another unit:

// Prompt the user for the length in centimeters
var lengthInCm = prompt('Enter the length in centimeters:');

// Prompt the user for the unit to convert to
var unit = prompt('Enter the unit to convert to (a or b):');

// Convert the length to the specified unit using the switch-case method
switch(unit) {
case 'a':
var lengthInMm = lengthInCm * 10;
alert(lengthInCm + ' cm is equal to ' + lengthInMm + ' mm');
break;
case 'b':
var lengthInM = lengthInCm / 100;
alert(lengthInCm + ' cm is equal to ' + lengthInM + ' m');
break;
default:
alert('Invalid unit');
break;
}

In this script, the user is prompted to enter the length in centimeters and the unit they want to convert to. The script then uses a switch-case statement to perform the conversion based on the user's choice. The result is displayed using the alert function.
