Your function should do this:

// make an array from 0 to 5
range`5` // => [0, 1, 2, 3, 4, 5]

// make an array from 10 to 15
range`10:15` // => [10, 11, 12, 13, 14, 15]

// can be filterred
range`1:50${x => x%10 === 0}` // => [10, 20, 30, 40, 50]

and must return [] if it's not valid like these examples:

range`1:` // => [] no end
range`:5` // => [] no start
range`1:5${true}` // => [] must be a function
range`1 : 10${x => x%2===0}` // => [] contains spaces
range`1:10${()=> true}${()=> true}` // => [] multiple functions

Note:

For range`n:m`, it'll always be 0 <= n < m
