simple-fmt.js

A maximally minimal string formatting library. Use it to make your code more readable compared to plain old string concatenation using +. The code is shorter than the MIT license text so it doesn't hog you down and you can use it everywhere. Works in node and browsers.

Usage

var fmt = require("simple-fmt");
console.log(fmt("hello {0} of age {1}", name, age));

instead of

console.log("hello " + name + " of age " + age);

because string formatting with + makes your eyes bleed and fingers hurt.

There's also fmt.obj(string, obj) and fmt.repeat(string, n):

var o = {name: "xyz", age: 42};
fmt.obj("hello {name} of age {age}", obj);
fmt.repeat("*", 3); // "***"

That's it.
