Using a value of 0 or 1 ensures-- that all JSON numeric data becomes strings in Lua.---- Note that unlike-- JSON.decodeNumbersAsObjects = true-- this stringification is simple and unintelligent: the JSON number simply becomes a Lua string, and that's the end of it.-- If the string is then converted back to JSON, it's still a string.
String interning is supported by some modern object-oriented programming languages, including Java, Python, PHP (since 5.4), Lua [4] and .NET languages. [5] Lisp , Scheme , Julia , Ruby and Smalltalk are among the languages with a symbol type that are basically interned strings.
It supports only a small number of atomic data structures such as Boolean values, numbers (double-precision floating point and 64-bit integers by default) and strings. Typical data structures such as arrays , sets , lists and records can be represented using Lua's single native data structure, the table, which is essentially a heterogeneous ...
The English Wikipedia has several templates and Lua modules which can format or manipulate strings.In this context a "string" is any piece of text forming part of a page. This help page covers a few useful techniques; look in the navbox below for the full catalogue of templa

Values are interpreted as strings unless tonumber (value) isn't nil, i.e. numbers should be converted to the numeric type. No effort is made to interpret tables. No effort is made to interpret tables.
A helper function that can be called from other Lua modules, but not from #invoke. This takes a string or a number value as input, and if the value can be converted to a number, cleanNumber returns the number and the number string. If the value cannot be converted to a number, cleanNumber returns nil, nil.
Note: Lua patterns are not regular expressions in the traditional POSIX sense, and they are not even a subset of regular expressions. But they share many constructs with regular expressions (more below). Lua patterns are used to define, find and handle a pattern in a string. It can do the common search and replace action in a text, but it has ...
