Making Decisions in your Code - Conditionals

Reading

• Making Decision in Your Code - Conditionals

if…else

if (condition) {
  /* code to run if condition is true */
} else {
  /* run some other code instead */
}

• if() designates the if function
• The statement evaluates the conditional statement for true or false
• If true, the code executes
• If false, the else code executes

else if

• Provides a chain of extra conditional statements to evaluate for true and false conditions

if (condition) {
  /* code to run if condition is true */
} else if (another condition) {
  /* code to run if condition is true */
} //exit if statement and run code below

Switch Statements

• Used when if…else statements would be extremely cumbersome
• Allow you to define multiple cases and run code based on the case

switch (expression) {
  case choice1:
    run this code
    break;

  case choice2:
    run this code instead
    break;

  // include as many cases as you like

  default:
    actually, just run this code
}
