An if statement in NodeJS has the following structure.
if (condition) {
<do something>
} else if (condition) {
<do something>
} else {
<do something>
}
For example.
if (foo == "Hello") {
console.log("foo equals Hello");
} else if (foo == "World") {
console.log("foo equals World");
} else {
console.log("foo does not equal Hello or World");
}
Following are command if statements.
