How js displays differential comparison of git
In software development, Git is a widely used version control system. It allows developers to better manage code libraries, track differences between different code versions, assist team collaboration, etc. At the same time, JavaScript is an increasingly important language and can be widely used in web, mobile and back-end development. In actual development, we often need to compare different code versions in Git and show the differences between them.
This article will introduce how to use JavaScript to display Git's differential comparison.
1. Prerequisite knowledge
Before learning how to display the differential comparison of Git, you need to have the following prerequisite knowledge:
- Basic knowledge of Git
Git is a distributed version control system that can store historical versions of a project and support comparison and modification from one version to another. There are three areas inside Git: local working directory (Working Directory), staging area (Stage), and local warehouse (Repository).
- Basic knowledge of HTML and CSS
HTML and CSS are basic skills in web front-end development. HTML is used to create the content of a web page, and CSS is used to define the style of a web page. In this article, we will use HTML and CSS to create and format the output of a differential comparison.
2. Use JavaScript to complete the differential comparison of Git
In JavaScript, there is a powerful library called jsdiff, which can be used to display the differential comparison of two pieces of text on a web page. jsdiff uses an auxiliary string-based algorithm to calculate the differences between two strings and prints these differences in the console.
The following is the basic method of using jsdiff:
const leftText = 'Hello world!'; // 第一个字符串 const rightText = 'Hellp world.'; // 第二个字符串 // 使用 diffChars 对两个字符串进行比较 const diffResult = diffChars(leftText, rightText); console.log(diffResult); // 输出结果
The above code snippet uses the diffChars method to compare two strings and stores the comparison results in diffResult in variables. We can see the output in the console, which will show the difference between each character.
Next, we will display the differential comparison results of Git on the HTML page. The sample code is as follows:
<html>
<head>
<title>Git差异化比较</title>
</head>
<body>
<h1>Git差异化比较</h1>
<div id="diffContainer"></div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/diff-dom/4.0.1/diffDOM.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jsdiff/4.0.1/diff.min.js"></script>
<script>
function showDiff(left, right) {
const diff = new diffDOM(); // 创建 diffDOM 实例
const leftElem = document.createElement('div'); // 创建左侧文本的 DOM 元素
const rightElem = document.createElement('div'); // 创建右侧文本的 DOM 元素
leftElem.textContent = left; // 设置左侧文本
rightElem.textContent = right; // 设置右侧文本
const diffResult = diff.diff(leftElem, rightElem); // 计算差异
// 将结果添加至页面
const diffContainer = document.getElementById('diffContainer');
diffContainer.appendChild(diffResult);
}
const leftText = 'hello world!';
const rightText = 'hello from the other side!';
showDiff(leftText, rightText);
</script>
</body>
</html>
In the above code, we use the diffDOM library to render the results of differential comparison and display it on the page. We compare the two strings on the left and right through the showDiff function and add the results to the diffContainer element.
Finally, we can view the results in the browser to understand Git's differential comparison results.
3. Summary
This article introduces how to use JavaScript to display the differential comparison of Git. We learned how to use the jsdiff library to compare two strings and output the comparison results. At the same time, we also used the diffDOM library to render the differential comparison results and display the comparison results in the HTML page.
By studying this article, you should be able to correctly use JavaScript to compare different code versions in Git and display the differences between them, thereby developing software more efficiently.

Git vs. GitHub: Version Control and Code Hosting
Apr 11, 2025 am 11:33 AM
Git is a version control system, and GitHub is a Git-based code hosting platform. Git is used to manage code versions and supports local operations; GitHub provides online collaboration tools such as Issue tracking and PullRequest.
Is Git the same as GitHub?
Apr 08, 2025 am 12:13 AM
Git and GitHub are not the same thing. Git is a version control system, and GitHub is a Git-based code hosting platform. Git is used to manage code versions, and GitHub provides an online collaboration environment.
Is GitHub difficult to learn?
Apr 02, 2025 pm 02:45 PM
GitHub is not difficult to learn. 1) Master the basic knowledge: GitHub is a Git-based version control system that helps track code changes and collaborative development. 2) Understand core functions: Version control records each submission, supporting local work and remote synchronization. 3) Learn how to use: from creating a repository to push commits, to using branches and pull requests. 4) Solve common problems: such as merge conflicts and forgetting to add files. 5) Optimization practice: Use meaningful submission messages, clean up branches, and manage tasks using the project board. Through practice and community communication, GitHub’s learning curve is not steep.
Should I put Git or GitHub on my resume?
Apr 04, 2025 am 12:04 AM
On your resume, you should choose to write Git or GitHub based on your position requirements and personal experience. 1. If the position requires Git skills, highlight Git. 2. If the position values community participation, show GitHub. 3. Make sure to describe the usage experience and project cases in detail and end with a complete sentence.
Does Microsoft own Git or GitHub?
