JavaScript branches

the decision makers (the "case" makers)

Branches make decisions with data based on cases:

if

Accounting for a situation:

if (x == true) {
    // if x is true, do something
}

// if it isn't, do nothing

if/else

Accounting for an either-or situation:

if (x == true) {
    // if x is true, do something
} else {
    // or else, do something else
}

if/elseif/else

Accounting for a non-binary situation:

if (x > 100) {
    // if x is above 100, do something
} else if (x > 50) {
    // if x is between 50-100, do something else
} else {
    // otherwise, do something completely different
}

switch

A more aesthetically-pleasing "synonym" of the if/elseif/else structure:

switch (x) {
    case (x > 100):
        // do something
        break;
    case (x > 50):
        // do something else
        break;
    default:
        // do something completely different
}
