Find JavaScript Code Snippets by Functionality with Cocycles

Cocycles: A new service that searches code by function

Core points:

• Cocycles is a new code search service that allows developers to search based on code functionality, with the goal of cataloging all open source code and making it easy to access.
• The service uses natural language processing algorithms to understand the required code description and converts the query into the required code functionality. JavaScript is currently supported and other languages ​​are planned to be added later this year.
• In addition to finding code snippets, Cocycles also provides an interactive exploration mode that allows users to interact with the code, view the complete source code implementation, and learn from actual usage examples.

We've all experienced this: having to leave the code editor, interrupt the workflow, open the browser to search for code snippets or explain how to write some code. This can be a time-consuming and frustrating process.

For many years, I have found myself spending most of my time using familiar search engines like Google and Bing, submitting queries like "JavaScript parsing HTTP headers" and praying that someone has asked this question somewhere, and Others have provided useful answers and even available code snippets.

Google and Bing understand English well, but they can't read the code. Sometimes luck is on our side, sometimes it is not.

However, this is not necessarily the case. In April 2016, GitHub reported that it has more than 35 million code bases. That's a lot of lines of code! I bet that most of the content that developers search every day already exists somewhere on the open source network. So far, the problem is that we can't find it easily. This is why we build Cocycles (a code search engine). In this article, I will introduce this new tool, explaining how it works and how to use it.

Cocycles: A function-based code search engine

The most important feature of Cocycles is to organize knowledge and make it accessible. What Cocycles does is easy to describe, but it is extremely challenging: it desires to find every part of the code in the open source world, catalog it, and make it easy to find and use. Therefore, it needs to do three things:

Understand the actual role of each piece of code

1. Understand what you actually want to find
2. Match the two and wait for "thank you" the flowers.
In fact, this is an ongoing process, and community collaboration is the key to it.

Cocycles is a technique to learn to understand the role of each piece of code. It not only looks at the signature, text or document of the code, but mainly looks at its functionality. Cocycles understands code and its functions. It is actually able to tell which code is best suited to swap two elements in a given array, or create random strings, and be able to recognize them, and even understand the connection between different parts.

It currently supports JavaScript and plans to add other languages ​​later in 2016.

Search code in pure English

Cocycles can understand English. It is also designed to understand the developer. To achieve this, Cocycles uses natural language processing algorithms to understand the code description you need and find what you want. So, when searching through Cocycles, it is best to describe your needs in the same way as searching in search engines such as Google, Bing, etc. However, unlike these search engines, Cocycles understands the code and therefore converts your query into the required code functionality.

For example, if you need to swap two elements in a given array, you just search for "swap elements". If you need to parse the header of an HTTP request, search for "Parse HTTP Header". When looking for a function that creates a random string, try searching for "Create Random String".

Cocycles can also understand that "String" is the same as "Str", and "Create" may mean "Generate". Additionally, you can try to find a wider range of content, such as "timers" and find useful timer classes with different methods.

Another clever feature is called "Cocycles Instant". When Cocycles knows exactly what you want to look for, it provides a real-time description of the desired result along with important key information—as shown in the following image, which shows a search for "angular isStr":

Learn how code works

When opening the result unit, Cocycles will take you into an IDE-like interactive exploration mode. It not only allows you to view the full source code implementation itself, but also interact with the code. Hovering over certain sections highlights the matching section; clicking on a variable or function will move you to its definition; it will soon be able to jump between files and even entire projects. This brings Cocycles from the world of “code snippets” into the world of learning, exploring and making code useful. This final view will adapt to various types of results. For example, if the result selected is a class, Cocycles will list its methods and provide a quick browsing between them.

If available, Cocycles will also provide complete original documentation for each code unit found. What's even cooler is that it will find actual usage examples from which you can learn how to use the found code and how others use it. If necessary, you can also view the source code of the code directly in GitHub.

Looking forward

Cocycles are not perfect. The technical challenges are huge. It is a process, and a process of continuing to work to organize all the code in the world and make it accessible.

It was built with the help of the community and based on the advice of some leaders in the online community. It is free and built for durability.

We also learn that the future lies in providing more value to people – by leveraging more potential hidden in the open source world.

For example, we should be able to real-timeidentify when a developer made a mistake or wrote less than ideal code. We need to be able to provide instant solutions based on open source code. We are currently working on something that will offer all of this and more. If you want to receive update notifications, you can subscribe to our newsletter and Twitter subscription.

You can use it and any feedback, thought or idea will be welcome. Visit cocycles.com and tell us what you think!

FAQs about JavaScript code snippets (FAQ)

What is the meaning of JavaScript code snippets?

JavaScript code snippets are small reusable code blocks that can be inserted into larger software systems. They are crucial for developers because they save time and effort by providing ready-made solutions for common programming tasks. These code snippets can range from small functions to complex algorithms and can be easily modified to suit specific requirements. They can also be an excellent tool for beginners to learn how different JavaScript functions work.

How to use CoCycles to find JavaScript code snippets by function?

CoCycles is a search engine designed specifically for finding code snippets. You can use it to find JavaScript code snippets by function. Simply enter the function you are looking for in the search bar and CoCycles will provide you with relevant code snippets. If you want to find JavaScript-specific snippets, you can also filter the results by language.

What JavaScript code snippets do every developer must know?

There are several JavaScript snippets that every developer should be familiar with. These include code snippets for array operations, string operations, date and time operations, and event processing. For example, a common snippet of code used for array operations is the "map" function, which calls each element in the calling array using the provided function and creates a new array containing the results.
