Javascript Single Quote vs Double Quote

If you don’t know where to use single quotes and where to use double quotes, this article will help you. We use both single quotes(”) and double quotes(“”) in javascript to define a string, but there are some differences between the two, let’s see what they are.  So, in this article, we’ll see javascript single quote vs double quote

If you want to display single quotes for a word in a sentence, put the sentence in double quotes and the word in single quotes. For example:

document.write("This is the 'example' sentence")

Similarly, if you want to display double quotes for a word in a sentence, you should set the sentence in single quotes and put the word only in double-quotes.

document.write('This is the "example" sentence')

You can also use the escape character backslash ‘\‘ for both of them, like:

document.write('This is the \'example\' sentence');
document.write('It\'s a beautiful day.')

We can use single quotes to store single characters or strings in a variable. You can use the single quotes to store the empty string ”,

inpBox.value = ' '

You can also store the tags in Javascript variables like

let link = '<a href="' + url + '">Click here</a>'; 
// Double quotes for HTML attribute, single quotes for JavaScript string

When working with JavaScript code that generates HTML or CSS, using single quotes for JavaScript strings can help maintain consistency with the widespread use of single quotes in HTML attributes and CSS selectors. For example:

let element = document.querySelector('.my-element'); // Single quotes in CSS selector
element.setAttribute('data-value', '123'); // Single quotes in HTML attribute

Using Template Literals:

let name = "John";
let message = `Hello, ${name}!`; // String interpolation with ${}
console.log(message); // Output: Hello, John!
