Mismatched input 'to' expecting 'end of line without line continuation'

compareFunction(start, len) =>
    for i = start to len
        if not long
            if x[1] < x[i]
            false
        else
            if x[1] > x[i]
            false
    true

where is the problem, I can’t understand

>Solution :

The false statements under your if statements are not properly indented.

It should be like this:

compareFunction(_start, _len) =>
    for i = _start to _len
        if not long
            if x[1] < x[i]
                false
        else
            if x[1] > x[i]
                false
    true
