October 27, 2025, changes effective October 31, 2025

JavaScript Content Updates

Dear Learners, we have upcoming updates for some of our JavaScript-based content, which will go live on October 31, 2025.

This round of updates targets two groups of content: Testing and Catchall. The primary goal of these updates is to upgrade the version of Node.js used in workspaces from older versions (7, 10, 14, 20) to version 22. Additionally, we will upgrade the various Node packages used within our workspaces and update workspace code to realign with any syntax changes and new best practices.

Selections from both the Testing and Catchall groups surface within these Career Journeys:

Testing

We will update our JavaScript Testing content within the following courses:

Note on feature-level testing: Our feature-level testing content relies on WebdriverIO, an open-source framework that can be used for testing the front-end of a web application. Since this content was created, WebdriverIO has undergone substantial changes, meaning the current instructional content and code we have are not compatible with up-to-date versions.

We are planning to create new content on feature-level testing in the future — learners enrolled in relevant content will be notified when this happens. In the meantime, because the existing content is so outdated, we have chosen to remove it from our catalog, even though there is no immediate replacement.

Note on model testing with MongoDB: While our model testing content with MongoDB surfaces in some of the same containers as our other JavaScript Testing content, the presence of a MongoDB server in the workspace requires additional considerations that fall outside the scope of this work. As such, our MongoDB content will not be receiving these updates at this time.

Catchall

This group includes most of our remaining JavaScript-based content that has not already been updated to Node version 22 or newer.

We will update our JavaScript content within the following courses and paths:


Happy coding!

September 23, 2025, changes effective September 30, 2025

Node Content Updates

Dear Learners, we have upcoming updates for our Node.js content, which will go live on September 30, 2025.

This round of updates targets content that specifically covers topics related to Node.js. As such, all of the content within Learn Node.js was included in this evaluation.

The primary updates are:

  • upgrading the environments from Node version 14 to Node version 22
  • addressing syntax and feature changes that result from the Node version upgrade

These changes relate to the interactive content (i.e., lessons, projects, and coding assessments) from the following tracks:

Selections of the same content also surface within these Career Journeys:

We are also updating the prerequisites of Learn Node.js. Previously, we recommended taking Learn JavaScript before taking Learn Node.js. Moving forward, to ensure that learners are adequately prepared, we also recommend taking Learn Intermediate JavaScript.


Additionally, we will be adjusting ALL content as needed to realign with internal standards. Since Node.js is often used to create back-ends for web applications, some of the more generic content, such as a non-coding lesson on back-end architecture and articles on JSON and REST, appear in content that covers other back-end technologies. In addition to the containers listed previously, such items appear in the following courses/paths:

There is also overlap with the following tracks for content regarding modules in Node:


Happy coding!
