In HTML, we can use the 0c6dc11e160d3b678d68754cc175188a tag to perform line breaks. But in JavaScript, we need to use a different method to achieve line breaks.

In JavaScript, we usually use `
` to represent a newline character. This symbol is called the "newline escape character" and it tells JavaScript to insert a newline character here, thereby wrapping the text.

For example, if we want to output two lines of text in JavaScript, we can write like this:

console.log("这是第一行
这是第二行");

The output result is:

这是第一行
这是第二行

The `
` here represents a Newline character, which separates the first and second lines of output.

In addition to using `
` when outputting text to the console, we can also use it to achieve line breaks when dynamically generating text through JavaScript on a web page.

For example, we can use the document.createElement function to create a new e388a4556c0f65e1904146cc1a846bee element, and then divide the text that needs to be wrapped into multiple paragraphs, in each Insert a 0c6dc11e160d3b678d68754cc175188a tag at the end of each paragraph, and finally add these paragraphs to the e388a4556c0f65e1904146cc1a846bee element in order to achieve the line break effect.

var text = "这是第一行
这是第二行
这是第三行";
var lines = text.split("
"); // 将文本按照换行符分成多个段落
var p = document.createElement("p");
for (var i = 0; i < lines.length; i++) {
  p.appendChild(document.createTextNode(lines[i])); // 添加文本节点
  if (i < lines.length - 1) {
    p.appendChild(document.createElement("br")); // 添加换行标签
  }
}
document.body.appendChild(p); // 将段落添加到网页中

In this way, we can achieve the line wrapping effect of multi-line text on the web page.

In short, to achieve line breaks in JavaScript, you can use the `
newline escape character, or use the HTML
` tag to dynamically generate text to achieve the line break effect.
