Syntax rules

For the full set of variable / identifier / assignment rules, see Syntax & Grammar.

A variable is a named reference to a value. Assigning a value the first time both declares and initialises the variable.

Variable declaration

<var_name> = <value>;

Rules:

• Identifier pattern: [a-zA-Z_][a-zA-Z_0-9]* — must start with a letter or underscore.
• No type prefix inside the function body. The type is auto-detected from the assigned value. Types are only allowed on the function signature.
• The value can be a literal, an expression, or another variable.

// WRONG — type prefix in bodyString name = "Asset";Number count = 10;
// RIGHTname = "Asset";count = 10;

Assignment forms

Three left-hand-side (LHS) forms are supported:

// 1. Simple variablename = "Asset";
// 2. Bracket access (key is any expression)data["title"] = "Inspection";items[0] = "first";
// 3. Dotted access (multi-level)record.priority.name = "High";
