Write a templating function that transforms strings like:
hello {{ world }} how is your {{ weekday }} going?
into a function that takes an object and returns a rendered string like so:
var tpl = your_function("hello {{ world }} how is your {{ weekday }} going?")
tpl({
world: 'dude'
, weekday: 'tuesday'
}) // == "hello dude how is your tuesday going?"
You'll need:
- RegExp literals
/\{\{\s*(\w+)\s*\}\}/ - String slice, replace
- To understand how to create lists of functions.
Put your code into a file called index.js and export the template function.
You'll need to write tests: use the assert module
to make sure your code works. Put this code in a file called test.js.
