Literals

In BoxLang, literals are fixed values that are not variables and do not change. Here are the types of literals in BoxLang:

1. String literals: These are sequences of characters. In BoxLang, you can denote them using single or double quotes. For example, "Hello, World!" or 'Hello, World!'.
2. Numeric literals: These are integer or floating-point numbers. For example, 123, 456.789.
3. Boolean literals: These represent truth values and can be either true or false.
4. Null literal: This represents a null value and is denoted by null.
5. Array literals: These are denoted by square brackets [] and can contain a list of values. For example, [1, 2, 3].
6. Struct literals: These are denoted by curly braces {} and can contain key-value pairs. For example, { "key1": "value1", "key2": "value2" }. An ordered (linked) struct literal can be accomplished using square braces in lieu of curly: [ "key1": "value1", "key2": "value2" ].
7. Date/Time literals: These represent a specific point in time. Strings which contain parseable dates can be interpreted as date/time objects in certain contexts. For example, dateFormat( "2024-05-12", "MM/dd/yyyy" ) will be operated upon as a date object. Note, however, that member date/time functions are not immediately available on a string literal.
8. Query literals: These are used to create a query object. They are represented in the format queryNew("column1,column2", "type1,type2", [ [ "data1", "data2" ] ]).

Remember, the way literals are used can vary depending on the context within the BoxLang code.
