Conditionals

Allows for conditional execution of code. Either one condition or multiple can be used, example:

if ( expression ) {  // Code}

Or with an else condition. When the expression evaluates to false, the else block will be executed:

if ( expression ) {  // Code} else {  // Code when expression was false}

Or, even more else conditions:

if ( expression ) {  // Code} else if ( expression ) {  // Code} else if ( expression ) {  // Code} else {  // Code when not a single expression equals to true}
// or, withour parenthesis
if expression  {  // Code} else if expression {  // Code} else if expression {  // Code} else {  // Code when not a single expression equals to true}

When the "expression" results in a boolean with the value "true", the code inside of the if-expression will be executed.

You can write a if-expression with and without the parenthesis around it. In the documentation we use without as the default and we encourage you the user to do the same.

Examples:

Lets take a look at a real example:

foo := 3if foo == 3 {  println(foo)}else {  println("Is not three")}

This code will result in the number three being printed in the terminal. That is because the variable "foo" has the value of three, and foo equals 3.

Expression

Since conditionals statements in Loop are not statements, but actually expressions, they evaluate to a value. This allows you to do things like this:

foo := if true {  "true"}else {  "false"}
