+## Convert a String to a Number!

+
+Note: This kata is inspired by Convert a Number to a String!. Try that one too.
+
+Description
+We need a function that can transform a string into a number. What ways of achieving this do you know?
+
+Note: Don't worry, all inputs will be strings, and every string is a perfectly valid representation of an integral number.
+
+Examples
+
+```js
+"1234" --> 1234
+"605"  --> 605
+"1405" --> 1405
+"-7" --> -7
+```
