The definitive Abstract Syntax Tree (AST).
Serves as the central data structure for parsing, analysis, transformation, and code generation.

• Install

  npm install @je-es/ast

  import * as AST from "@je-es/ast";

  
  
  

• Usage

  // suppose we want to represent an abstract syntax tree for this statement:
  pub let mut x: i32 = 42

  const my_let_stmt = AST.StmtNode.asLet(
      // span
      { start: 0, end: 23 },
  
      // Public/Static/Private
      {
          kind: 'Public',
          span: { start: 0, end: 3 },
      }
  
      // Comptime/Runtime
      {
          kind: 'Runtime', // default
          // span: undefined,
      }
  
      // Mutable/Immutable
      {
          kind: 'Mutable',
          span: { start: 8, end: 11 },
      }
  
      // ident
      AST.IdentNode.create({ start: 12, end: 13 }, 'x'),
  
      // type
      AST.TypeNode.asSigned({ start: 15, end: 18 }, 'i32'),
  
      // init
      AST.ExprNode.asInteger({ start: 21, end: 23 }, 42)
  );
