You can try the tagged template as seen below, and you’ll notice you get the same output as if you omitted normal. You can use the ${expression} notation for that. It’s called the “rest parameters syntax”, and it’ll basically place all the arguments passed to normal that come after template into a single array.
Let’s dig into template literals and see what we can come up with. Please consider disabling your ad blocker on Pony Foo. Now that we’ve figured out how tagged templates work, what can we do with them? One possible use case might be to make user input uppercase, turning our greeting into something that sounds more satirical – I read the result out loud in my head with Gob’s voice from Arrested Development, now I’m laughing alone. If you use template literals for templating, you often write code like this: The problem is that the output is not properly indented: That’s because the line breaks inserted via join() are not followed by the correct indentation. const blankSpace = ` first second third `; Here's the output. In this case we can reduce the template starting from template[0] and then reducing all other parts by adding the preceding expression and the subsequent part. This can be very convenient in some use cases.
If you are using template literals only with placeholders (e.g. The first is something, the string until the first interpolation, and the second is an empty string, the space between the end of the first interpolation (we only have one) and the end of the string. I denoted the white space with a dot, ⚪️ and line break with a square ️: Reduce is always useful when you’re trying to map a collection of values into a single value that can be computed from the collection. Any newline characters inserted in the source are part of the template literal. These ads help pay for my hosting.
No need for join(), anymore: Alas, common-tags does not indent inserted strings correctly: The line break between the and the
- Pony Foo has been online for a while. they offer a great syntax to define multiline strings, they provide an easy way to interpolate variables and expressions in strings, they allow you to create DSLs with template tags (DSL means domain specific language, and it’s for example used in React by Styled Components, to define CSS for a component).
