Azure JavaScript libraries preview release

Today, we are happy to announce the first preview release of Azure JavaScript libraries generated from the [Azure REST API specs](https://github.com/Azure/azure-rest-api-specs) using [AutoRest](https://github.com/Azure/AutoRest). This release adds support for isomorphic JavaScript libraries with TypeScript definitions that work on both server and client (browser). The new libraries are released under @azure scope, and package names are in the following pattern: @azure/arm-<servicename> (for Azure Resource Manager libraries) and @azure/<servicename>. You can find the new repository on [GitHub](https://github.com/Azure/azure-sdk-for-js). The current plan is to release a stable version of the Azure JavaScript libraries by the middle of next year. After the stable release of Azure JavaScript libraries, the [Azure node libraries](https://github.com/Azure/azure-sdk-for-node#azure-service-modules) will be deprecated. For guidance on how to migrate from the old Azure node libraries to the new Azure JavaScript libraries, see the [migration page](https://github.com/Azure/azure-sdk-for-js/blob/master/documentation/Migration.md). For help, see the code snippets in the readme under [packages/@azure](https://github.com/Azure/azure-sdk-for-js/tree/master/packages/%40azure) folders – for example, the [arm-compute folder](https://github.com/Azure/azure-sdk-for-js/tree/master/packages/%40azure/arm-compute). * Azure Resource Manager * SDKs * SDK and Tools * [ Azure Resource Manager](https://azure.microsoft.com/en-gb/get-started/azure-portal/resource-manager/)
