format(object)

Yet another templating function. Sorry, but it was a great idea 10 years ago. The associated String is a template using either ${key} or {key} for placeholders. Takes an object, key/value pairs, as input. If a key matches a key in a placeholder, the associated value replaces the placeholder.

var pattern = "The {team} will win the {contest} in the {season} season.";
var str = pattern.format({ team: 'Texas Rangers', contest: 'World Series', season: 2010});  
// str equals "The Texas Rangers will win the World Series in the 2010 season.".
