+# --description--
+
+The [Look and say sequence](https://en.wikipedia.org/wiki/Look and say sequence) is a recursively defined sequence of numbers.
+
+Sequence Definition
+
+<ul><li>Take a decimal number</li>
+<li><span>Look</span> at the number, visually grouping consecutive runs of the same digit.</li>
+<li><span>Say</span> the number, from left to right, group by group; as how many of that digit there are - followed by the digit grouped.</li></ul><span> This becomes the next number of the sequence.</span>
+
+An example:
+
+<ul><li>Starting with the number 1, you have <span>one</span> 1 which produces 11</li>
+<li>Starting with 11, you have <span>two</span> 1's. I.E.: 21</li>
+<li>Starting with 21, you have <span>one</span> 2, then <span>one</span> 1. I.E.: (12)(11) which becomes 1211</li>
+<li>Starting with 1211, you have <span>one</span> 1, <span>one</span> 2, then <span>two</span> 1's. I.E.: (11)(12)(21) which becomes 111221</li></ul>
+
+# --instructions--
+
+Write a function that accepts a string as a parameter, processes it, and returns the resultant string.
+
+# --hints--
+
+`lookAndSay` should be a function.
+
+```js
+assert(typeof lookAndSay == 'function');
+```
+
+`lookAndSay("1")` should return a string.
+
+```js
+assert(typeof lookAndSay('1') == 'string');
+```
+
+`lookAndSay("1")` should return `"11"`.
+
+```js
+assert.equal(lookAndSay('1'), '11');
+```
+
+`lookAndSay("11")` should return `"21"`.
+
+```js
+assert.equal(lookAndSay('11'), '21');
+```
+
+`lookAndSay("21")` should return `"1211"`.
+
+```js
+assert.equal(lookAndSay('21'), '1211');
+```
+
+`lookAndSay("1211")` should return `"111221"`.
+
+```js
+assert.equal(lookAndSay('1211'), '111221');
+```
+
+`lookAndSay("3542")` should return `"13151412"`.
+
+```js
+assert.equal(lookAndSay('3542'), '13151412');
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+function lookAndSay(str) {
+
+}
+```
+
+# --solutions--
+
+```js
+function lookAndSay(str) {
+    return str.replace(/(.)\1*/g, function(seq, p1) {
+      return seq.length.toString() + p1;
+    });
+}
+```
