    Introduction

    Like String.prototype.match if it only checked the regex at the given index instead of searching the entire string.

    matchAt(/world/, 'hello world', 6);  // ['world']
    matchAt(/world/, 'hello world', 0);  // null

    Almost like 'hello world'.slice(i).match(/^world/) except the resulting match object's .index property corresponds to the original string, and it doesn't actually slice the string. Most engines optimize taking a substring so this probably isn't particularly valuable in practice, but it was an entertaining exercise and could be useful if you reminisce about these semantics.
