String Literals in JavaScript: Should I Use Double-quotes or Single-quotes?

• prettier

  439 48,241 9.8 JavaScript

  Prettier is an opinionated code formatter.

  

I can also highly recommend Prettier for maintaining a consistent coding style and fixing up existing source code.

• React

  1,691 221,535 9.8 JavaScript

  The library for web and native user interfaces.

  

Looking at some popular JavaScript projects on GitHub, I noted that react, moment, and express all use single quotes for strings. However, another popular project, tslib, uses double quotes 🙄. So, while it would seem that single quotes is more common, this metric is not entirely conclusive.

Now, regardless of whether you are decided on using single quotes or double quotes in JavaScript, the more important issue is applying your convention consistently throughout the code base. ESLint is one tool that will help a great deal in enforcing a consistent coding style. You supply it with a config file specifying a list of rules describing your coding conventions, and it will indicate where your code is not conforming to the specified rules.
