Question

How can we improve the following program?

function start() {
move();
move();
move();
move();
move();
move();
move();
move();
move();
}
JavaScript


Break down this program into more functions


Use a for loop to repeat the move command


Use a while loop to repeat the move command


Fix the indentation of this program

Answer 1

Some ways to improve the program are:

1. Break down this program into more functions:
Instead of having all the move() commands inside the start() function, it is better to separate them into smaller functions. For example:

function moveMultipleTimes(num) {
for (let i = 0; i < num; i++) {
move();
}
}

function start() {
moveMultipleTimes(9);
}

The moveMultipleTimes() function can be reused in other parts of the code as well.

2. Use a for loop to repeat the move command:
Instead of writing move() multiple times, a for loop can be used to repeat the move command a certain number of times. For example:

function start() {
for (let i = 0; i < 9; i++) {
move();
}
}

This reduces code redundancy and makes it easier to modify the number of times the move command is executed.

3. Use a while loop to repeat the move command:
Similar to using a for loop, a while loop can be used to repeat the move command until a certain condition is met. For example:

function start() {
let count = 0;
while (count < 9) {
move();
count++;
}
}

This approach allows more flexibility in terms of the condition to repeat the move command.

4. Fix the indentation of this program:
Proper indentation improves code readability and makes it easier to understand the program's structure. The code should be indented consistently for better readability. For example:

function start() {
move();
move();
// more move() commands...
move();
}
