For this type of module the TypeScript compiler can emit both ECMAScript 6 compliant code and down-level ECMAScript 3 or 5 compliant code for a variety of module loading systems, including CommonJS, Asynchronous Module Definition (AMD), and Universal Module Definition (UMD).

+The Symbol primitive type corresponds to the similarly named JavaScript primitive type and represents unique tokens that may be used as keys for object properties.
 
 The `symbol` keyword references the Symbol primitive type. Symbol values are obtained using the global object 'Symbol' which has a number of methods and properties and can be invoked as a function. In particular, the global object 'Symbol' defines a number of well-known symbols ([2.2.3](#2.2.3)) that can be used in a manner similar to identifiers. Note that the 'Symbol' object is available only in ECMAScript 6 environments.
