In python, I can do the following:

name = "bob"

print("Hey, %s!" % name)

Is there anything similar to that (or Python's .format()) in JavaScript/NodeJS?

  • You may consider using CoffeeScript it uses whitespace for block delimition like Python and has also list comprehensions. It doesn't provide string formatting but you can interpolate e.g. console.log("Hey, #{name}!") Commented May 29, 2012 at 2:19

You can use util.format, it's printf like function.

Another option is template strings

For example:

const name = "bob";
console.log(`Hey, ${name}!`);

sprintf should do what you are asking for I think.

But that just prints it, doesn't it? What if I want to do something like socket.send("NOTICE #channel :My name is %s" %(bot.name));?
No? I didn't think so I thought it returned a string
AFAIK sprintf is not part of node. It used to be a package, deprecated now. Answer by @Alex below should be considered valid.
The link is broken. This one should work: npmjs.com/package/sprintf-js
