World War Z++

Problem: Many things, such as death and taxes, are inevitable. Another thing that's inevitable, in the scope of this problem, is the Zombie Apocalypse. You are the lone survivor (good job, go you!), but you're stuck on the top floor of a warehouse (a vertical maze) full of the brain munching monsters. That sucks.

Rules: Build a function that runs through the maze, that takes into account not just walls, but also zombies. Luckily, zombies can't move (they're hungry, you don't like moving when you're hungry either, don't judge).

Moving:

• You can move one space in any direction (that you are able) during a step.
• You can move through gaps in the floor (" ").
• You will start at the S position and finish at the F position.
• You cannot move through walls (" | "), as they are solid.
• If you hit a wall, or a Zombie (" Z "), you will need to switch directions on the next step.

NOTE: You do not need to create a function to go up floors, but you are welcome to give it a shot for extra credit.

Requirements: Your function should take in the following maze grid (which is 12 rows by 10 columns), which is an array of strings. You do not need to rewrite this maze grid on a whiteboard (that would be cruel and unusual punishment), but it is here for your reference.

Example Maze Grid:

var mazeGrid = 
["         S  ",
"|________ __|",
"| _________Z|", 
"| Z_________|",
"| |_____Z___|",
"| _________Z|",
"|__ __Z_____|",
"|_____ ___Z_|",
"| |__| _____|",
"| ________Z_|",
" F           "]
