Extract the money

importance: 4

We have a cost in the form "$120". That is: the dollar sign goes first, and then the number.

Create a function extractCurrencyValue(str) that would extract the numeric value from such string and return it.

The example:

alert( extractCurrencyValue('$120') === 120 ); // true

Open a sandbox with tests.

function extractCurrencyValue(str) {
  return +str.slice(1);

Open the solution with tests in a sandbox.
