| // Basic logic-free string interpolation. | |
| // Usage: | |
| // format('Hello, {name}', {name: 'Bob'}); | |
| // > "Hello, Bob" | |
| // format('{0}'s favorite color is {1}.', ['Bob', 'green']); | |
| // > "Bob's favorite color is green." | |
| function format(string, values) { | |
| // Match tokens of the form {foo} or {0}. | |
| var regex = /\{([^}]+)\}/g; | |
| // Replace each matching token {foo} with values['foo']. | |
| return string.replace(regex, function(_, match) { | |
| return values[match]; | |
| }); | |
| } | |
| // Perform a partial application of the format function. | |
| // Allows for creation of named templates. | |
| // Usage: | |
| // var greeting = template('Hello, {name}'); | |
| // greeting({name: 'Bob'}); | |
| // > "Hello, Bob" | |
| function template(string) { | |
