If… Else If… Else

Sometimes it is helpful to execute a block of statements only if a certain boolean condition evaluates true. In this case, if statements can be used.

if(condition) {
    // do something
}

If you need an alternative case for if the condition is false, use else:

if(condition) {
    // do something
} else {
    // do something else
}

Lastly, sometimes it is helpful to chain different conditions together so that only one block is executed:

if(condition) {
    // do something
} else if(anotherCondition) {
    // do something else
} else if(anotherNotherCondition) {
    // a third thing
} else {
    // a last option
}

Remember that any block will only be executed if its condition is true and if all the conditions above it were false. If they are all false, then the else block is run.
