How to add new line in javascript

In JavaScript, you can add a new line in several ways:

Using the \n character: You can use the \n character to create a new line. For example:
```
console.log("Hello\nWorld");
```
This will output:
```
Hello
World
```
Using the   tag: You can use the   tag to create a new line. For example:
```
document.write("Hello World");
```
This will output:
```
Hello
World
```
Note that the   tag is only valid in HTML contexts, not in plain JavaScript.
Using the document.createElement method: You can create a new line by creating a   element using the document.createElement method. For example:
```
var br = document.createElement("br");
document.body.appendChild(br);
```
This will create a new line in the HTML document.
Using the String.prototype.split method: You can split a string into multiple lines using the split method. For example:
```
var str = "Hello World";
var lines = str.split("\n");
console.log(lines); // Output: ["Hello", "World"]
```
This will split the string into an array of lines.
Using the String.prototype.replace method: You can use the replace method to add a new line to a string. For example:
```
var str = "Hello World";
str = str.replace(/ /g, "\n");
console.log(str); // Output: "Hello\nWorld"
```
This will replace all spaces in the string with new lines.

Note that the above methods may not work as expected in all browsers or environments. It's always a good idea to test your code thoroughly to ensure it works as expected.
