This course focuses on Redis implementation with Node.js to develop scalable applications with high-performance. Whether you’re a beginner or an experienced developer, this course is an excellent resource to help you develop high-performance, scalable applications using Redis and Node.js.

In this course, you’ll get an introduction to Node.js and Express.js. You’ll learn about Redis in depth—including Redis commands, key patterns, transactions, and connecting Redis with Node.js through the Redis npm package. Then you’ll learn its practical implications via two projects to apply your skills. The first involves building a GitHub search project using Redis and Node.js to understand Redis caching and integrate GitHub APIs. The second includes building an API rate limiter using Redis and Node.js to comprehend Redis's use in limiting the number of API requests and managing API rate limits.

After taking this course, you’ll be able to develop high-performance, scalable applications using Redis and Node.js.

Building Scalable Apps: Redis Implementation with Node.js

Consider the following Redis operations using the `redis` npm package. What's the output of the following code?

```

console.log(reply)
``` 

Consider the following Redis operations using the <code>redis</code> npm package. What’s the output of the following code?
<pre><code>const reply = await redisClient.set('website', 'educative')
