the only issue is i'd like to differentiate between iterating arrays and objects at the syntax level. Coffeescript uses `in` for arrays and `of` for objects, but I agree that becomes confusing. Open to other suggestions!
These are legal CoffeeScript examples:
for key, value of object
if key of object
for value in array
if value in array
for index, value of array
if index of array
for value in object
if value in object every element as key, value from arr {
console.log(key, value);
}
every property as key, value from obj {
console.log(key, value);
} every [key, value] from arr {
console.log(key, value);
}
every {key, value} from obj {
console.log(key, value);
}
every [key] from arr {
console.log(key);
}
every {_, value} from obj {
console.log(value);
}
There's also the issue with some fonts making it hard to differentiate between { and [ but it's an idea that might be worth to think about at least.
fast-each [value] from arr {
}
fast-each {value} from obj {
}
fast-each [value, key] from arr {
}
fast-each {value, key} from obj {
}
Alternative:
fast-properties key, value from obj {
}
fast-elements index, value from arr {
}
fast-properties value from obj {
}
fast-elements value from arr {
}But if Coffescript can walk away with its choice then I don't think you'll have anything to worry about.
