How can I shorten these if-else statements?

edit

There are a few strategies you could try to shorten if-else statements:

1. Use ternary operators: If the if-else statement is simple enough, you can use a ternary operator to condense it. For example:

Original code:

if (x > 0) {
   y = x;
} else {
   y = 0;
}

Shortened code:

y = (x > 0) ? x : 0;

1. Combine conditions: Look for conditions that can be combined so that you have fewer if-else statements. For example:

Original code:

if (x > 0 && y > 0) {
   z = x + y;
} else {
   z = 0;
}

Shortened code:

z = (x > 0 && y > 0) ? x + y : 0;

1. Use switch statements: If you have multiple if-else statements that are checking the same variable, you can use a switch statement to condense the code. For example:

Original code:

if (x == 1) {
   y = 10;
} else if (x == 2) {
   y = 20;
} else if (x == 3) {
   y = 30;
} else {
   y = 0;
}

Shortened code:

switch (x) {
   case 1:
      y = 10;
      break;
   case 2:
      y = 20;
      break;
   case 3:
      y = 30;
      break;
   default:
      y = 0;
      break;
}

1. Use functions: If you have a long if-else statement that performs a specific task, consider breaking it out into a separate function. This can make your main code more readable and easier to follow. For example:

Original code:

if (x > 0 && y < 0) {
   z = x * y;
} else if (x < 0 && y > 0) {
   z = x + y;
} else if (x == 0 || y == 0) {
   z = 0;
} else {
   z = y / x;
}

Shortened code:

function calculateZ(x, y) {
   if (x > 0 && y < 0) {
      return x * y;
   } else if (x < 0 && y > 0) {
      return x + y;
   } else if (x == 0 || y == 0) {
      return 0;
   } else {
      return y / x;
   }
}

z = calculateZ(x, y);
