JavaScript Mapping for Sequences

On this page:

Basic JavaScript Mapping for Sequences

A Slice sequence maps to a native JavaScript array. This means that the Slice-to-JavaScript compiler does not generate a separate named type for a Slice sequence. It also means that you can take advantage of all the inherent functionality offered by JavaScript's array type. For example:

sequence<Fruit> FruitPlatter;

We can use the FruitPlatter sequence as shown below:

var platter = [Fruit.Apple];

JavaScript Mapping for Byte Sequences

As an optimization, occurrences of sequence<byte> map to a native buffer type, which is more efficient than native arrays for working with binary data. For browser applications, sequence<byte> maps to Uint8Array, and for Node.js applications it maps to the native Buffer type.
