getFirstDigit

Language/Type: JavaScript

Write a function named getFirstDigit that returns the first digit of an integer. For example, getFirstDigit(3572) should return 3.

Note: Because JavaScript integers are number types, dividing two integers which do not divide evenly returns the decimal value of the result instead of an integer (for example, 1 / 2 results in 0.5, not 0). Use parseInt(a / b) to parse the result into an integer if needed to solve this problem.

Function: Write a JavaScript function as described, not a complete program.
