+# Translate border-left-width to borderLeftWidth
+
+Write the function `camelize(str)` that changes dash-separated words like "my-short-string" into camel-cased "myShortString".
+
+That is: removes all dashes, each word after dash becomes uppercased.
+
+Examples:
+
+```js
+camelize("background-color") == 'backgroundColor';
+camelize("list-style-image") == 'listStyleImage';
+camelize("-webkit-transition") == 'WebkitTransition';
+```
+
+P.S. Hint: use `split` to split the string into an array, transform it and `join` back.
