Answer 1

The following function returns the complementary result of slice function:

 String.prototype.remainderOfSlice = function(begin, end) {

    begin = begin || 0
    end = (end === undefined) ? this.length : end 

    if (this.slice(begin, end) === '') return this + ''
    return this.slice(0, begin) + this.slice(end) 
 }

examples:

 "hi how are you".slice(2, 6) // " how"
 "hi how are you".remainderOfSlice(2, 6) // "hi are you"

 "hi how are you".slice(-2, 6) // ""
 "hi how are you".remainderOfSlice(-2, 6) // "hi how are you"
