Web-based services, including data services and applications, are central to modern GIS and making the most of these services invariably involves working with JavaScript. For GIS professionals using Esri technology, the ArcGIS API (Application Programming Interface) for JavaScript offers a rich array of capabilities to support web-based mapping application development and geoprocessing. The latest version of the API, Version 4.x, is a significant upgrade from Version 3.x and supports Esri's current web technology solutions, including the ArcGIS Online Map Viewer, Experience Builder, and Instant Apps. Learning JavaScript and the ArcGIS API for JavaScript allows GIS professionals to take advantage of the technology used in solutions such as these to develop their own custom applications and enrich their spatial data delivery and geoprocessing needs.

The purpose of this workshop is to help attendees get started with Version 4.x of the ArcGIS API for JavaScript. The workshop will cover four topics: (1) Core JavaScript principles pertinent to the API; (2) Use of Visual Studio Code, a rich, powerful, and free Integrated Development Environment (IDE); (3) Debugging code; and (4) Basic use of ESLint, an analysis tool for finding and fixing problems in JavaScript code. Attendees will apply what they've learned and evolve their programming skills by working through a series of application examples, each of which will demonstrate core capabilities of the API.

Intended Audience
GIS professionals familiar with basic JavaScript programming and wishing to develop applications using Version 4.x of the ArcGIS API for JavaScript.

Prerequisite Requirement
Attendees must have experience using JavaScript for simple web application (i.e., page) development. Experience with Version 3.x of the ArcGIS API for JavaScript will be helpful, but not strictly required. Please contact the instructor if you would like to attend the workshop, but have any concerns about the prerequisite requirements.

Associated Workshop
Completion of this workshop is required for anyone wishing to attend an associated workshop, "Getting Started with TypeScript and the ArcGIS API for JavaScript 4.x," to be offered at a later date. An exception to this requirement will be made if the instructor is satisfied that your level of experience with JavaScript and Version 4.x of the ArcGIS API for JavaScript is such that attending the initial workshop is not necessary. If required, please contact the instructor for further details.

Format and Technical Requirements
The workshop will consist of a balance between lecture material and demonstrations. Instructions for setting up the required software will be provided prior to the workshop.
