node --version # v18.x.x npm --version # 9.x.x or higher For developers who need multiple Node versions:
No more jest or mocha for basic use cases—Node 18 gives you a full test harness out of the box. Streaming data is critical for performance. Node 18 delivers the full Web Streams API ( ReadableStream , WritableStream , TransformStream ), making it compatible with the standardized web platform.
Node.js 18 has arrived—and it is a milestone release. Dubbed the “Full” version by many in the development community, Node 18 isn't just another incremental update. It represents a significant shift in how JavaScript developers build server-side applications, offering a complete toolset that merges stability with cutting-edge features. node 18 full
| Metric | Node 14 | Node 16 | Node 18 Full | | ------ | ------- | ------- | -------------- | | Requests/sec | 12,400 | 14,200 | | | Avg Latency (ms) | 78 | 69 | 58 | | Memory (MB) | 210 | 198 | 172 | | Startup Time (ms) | 145 | 138 | 124 |
const ReadableStream = require('node:stream/web'); const stream = new ReadableStream( start(controller) controller.enqueue('Hello '); controller.enqueue('World'); controller.close(); ); This is a game-changer for building high-performance data pipelines without third-party stream libraries. Node 18 adds server response timeout and better diagnostics channels. The full server.headersTimeout and server.requestTimeout properties allow fine-grained control over hanging connections. node --version # v18
Run it with: node --test
Node 18 delivers a comprehensive, production-ready platform that reduces external dependencies, improves performance, and aligns with modern web standards. The full package includes everything from a test runner to a Fetch API, making it a self-sufficient JavaScript runtime. | Metric | Node 14 | Node 16
If you are still on Node 14 or 16, migrate to Node 18 (both have reached end-of-life). If you are starting a new project, Node 18 provides a perfect balance of stability and modernity.
Probability calculations that can be used to inform decisions and manage risk can be very complicated. This unit is designed to help build your foundational understanding of probability and introduce you to some of the techniques that are used to calculate very difficult probabilities. You will continue to work with the Games Fair interactive tool and be exposed to real world situations to start to realize the impact of probability in your world.
The focus of this unit is on Probability Distributions. You will learn how to display all of the outcomes of a probability situation in a table and a bar graph. You will learn some formulas that will work with some situations. A large part of the unit will be calculating the expected value, or average, of a probability situation. The Games Fair Interactive tool will be used throughout the unit and will provide a focus for the summative and lead up to the Culminating Assignment, the Games Fair.

After much work to collect valid and reliable information in the form of statistics, you will learn to analyse the statistics to make conclusions that can help make decisions. You will explore one real and two variables statistics using the World Map Interactive tool. A data set used will include a perceived quality of Health Care across Canada. The unit summative will be require you to act as a consultant for a large Canadian franchise to help them make a decision.
In Unit 3 of this course, you demonstrated how to represent the distribution of a discrete random variable. This unit will look at the distribution of continuous random variables and how they are compared to discrete variables. In the third and fourth activity, you will be introduced to what may be the most important mathematical function: the normal distribution.
In this unit, you will consolidate the concepts and skills you have learned throughout this course. You will complete the course culminating activity, through which you will analyze the impacts of energy transformation technologies on society and the environment.
