I'm going through the CoffeeScript book by Trevor Burnham, and I was curious as to what the best style is for a function I was writing.In the book the author writes the function like so:strToCoordinates = (input) ->    halves = input.split(',')    if halves.length is 2        x = parseFloat halves[0]        y = parseFloat halves[1]        if !isInteger(x) or !isInteger(y)            console.log Each coordinate must be an integer.        else if not inRange x - 1, y - 1            console.log Each coordinate must be between 1 and #{GRID_SIZE}.        else            {x, y}    else        console.log 'Input must be of the form `x, y`.'I wrote my function like so:strToCoordinates = (input) ->    halves = input.split(',')    if halves.length isnt 2        console.log 'Please enter coordinates in format: x,y'; return    [x, y] = (parseFloat s for s in halves)    unless isInteger(x) and isInteger(y)        console.log 'The coordinates must be integers.'; return    if not inRange(x, y)        console.log Coordinates must be between 1 and #{GRID_SIZE}.; return    {x, y}Is my use of just if statements and using return to stop the flow if the check fails an okay style?I like the fact that with this style the error messages are right after the check unlike with if/else, and also you don't have to have large sections indented.
