str = replace('Hello, ${test}', { test : 'world' }); // Hello, world
str = replace('Hello ${test} foo ${bar}', { test : 'world', bar : 'biz' }); // Hello world foo biz
str = replace('The ${data.one} brown ${data.two} jumped', { data : { one : 'quick', two : 'fox' } }); // The quick brown fox jumped
