JavaScript Escape Double Quote

In this article, we will see how to escape double quote in javascript. We can print or log strings inside double quotes in javascript. If you try to print strings without using double quotes, the browser thinks we are trying to print a variable and returns an error. For example:

document.write("Hello Welcome")

Output:

javascript escape double quote
In this above example code, we have printed the string “Hello Welcome” inside the double quotes using the document.write() method. So, we got the string as an output.

document.write(Hello)

Output:

javascript escape double quote

In this above example, we print the string without using double quotes. So, it will return the error:

So, we must print the strings inside double quotes. If the string itself contains a double quote character, this can cause issues with the syntax of the code like :

document.write("Every "child" likes an ice cream");

In this case, the double quotes within the string itself are interpreted as the end of the string, causing a syntax error. So, we use the escape character to avoid this issue.

How to escape double quotes?

By using the backslash character ‘/’  to escape the double quotes within the string, we can ensure they are interpreted correctly. For example:

document.write("Every \"child\" likes an ice cream");

Output:

javascript escape double quote
In this example, we have printed the double quotes using the backslash escape character. See the code the double quotes are printed successfully.

Another way to escape double quotes in JavaScript is by using template literals. Template literals are a newer feature of JavaScript that allows for more flexible string interpolation, and they can also be used to avoid issues with escaping characters. To create a template literal, we enclose the string within backticks (`), and use ${} to insert variables or expressions into the string. For example:

document.write('Every "child" likes an ice cream');

In this case, the double quotes within the string are interpreted as literal characters, since they are enclosed within backticks rather than single or double quotes.

Conclusion

So, when working with strings in JavaScript, it is important to be aware of certain characters’ potential to cause syntax or unintended behavior issues. Double quotes can be particularly problematic, but can be escaped using the backslash character or by using template literals. By using these techniques, we can ensure that our strings are interpreted correctly and our code runs smoothly.
