Pythonic Dictionary String Interpolation with Javascript? [duplicate]

Researching some ways to generate a .tex file and subsequently a PDF, I found a beautiful pythonic method of string interpolation that I've never seen before, specifically in this SO question here:

import argparse

content = r'''\documentclass{article}
\begin{document}
... P \& B 
\textbf{\huge %(school)s \\}
\vspace{1cm}
\textbf{\Large %(title)s \\}
...
\end{document}
'''

parser = argparse.ArgumentParser()
parser.add_argument('-c', '--course')
parser.add_argument('-t', '--title')
parser.add_argument('-n', '--name',) 
parser.add_argument('-s', '--school', default='My U')

args = parser.parse_args()

with open('cover.tex','w') as f:
    f.write(content%args.__dict__) #This!

Is there any way of implementing the pythonic solution above in JavaScript?
