Tip 4: Variables to Readable Strings with Template Literals
Explore how to simplify string concatenation in JavaScript by using template literals. Understand how backticks and embedded expressions improve clarity when combining variables and strings, making your code cleaner and more maintainable. This lesson helps you create readable strings efficiently.
We'll cover the following...
Combining strings
Strings are messy. That’s all there is to it. When you’re pulling information from strings, you have to deal with the ugliness of natural language: capitalization, punctuation, misspellings. It’s a headache.
Collecting information into strings is less painful, but it can still get ugly quickly. Combining strings in JavaScript can be particularly rough, especially when you combine strings assigned to variables with strings surrounded by quotes.
Example
Here’s a situation that comes up all the time: You need to build a URL. In this case, you’re building a link to an image on a cloud service. Your cloud service is pretty great, though. In addition to hosting the asset, you can pass query parameters that will convert the asset in a variety of ways (height, width, and so on).
