JavaScript equivalent of Python's parameterised string.format() function

Question

Here is the Python example

>>> 'Coordinates: {latitude}, {longitude}'.format(latitude='37.24N', longitude='-115.81W')

'Coordinates: 37.24N, -115.81W'

I am looking for a way to emulate this behavior in JavaScript. As I have plenty of templates strings as """{} lorem {} ipsum""" and bunch of JSON objects as k,v pairs that correspond to parameters & values.

I hate to implement my own parser if something equivalent already exist. Any similar libraries would be much appreciated.

You can consider using template strings for this purpose.

In JavaScript this is called Template Literals. You can read about it here. It works similar to the Python format function but its done inline.

`string text ${some_variable} string text`

Where the ` back tick starts and ends the string. Inside the back ticks any ${variable} will be converted to the value of the variable. Just make sure the variable is in the scope of the string you are trying to format.

Except it seems to lack all the template arguments that let Python actually control the format? Right-align, left-align, control padding character, etc.
