[javascript] JavaScript Array splice vs slice

The difference between Slice() and Splice() javascript build-in functions is, Slice returns removed item but did not change the original array ; like, 

        // (original Array)
        let array=[1,2,3,4,5] 
        let index= array.indexOf(4)
         // index=3
        let result=array.slice(index)
        // result=4  
        // after slicing=>  array =[1,2,3,4,5]  (same as original array)

but in splice() case it affects original array; like,

         // (original Array)
        let array=[1,2,3,4,5] 
        let index= array.indexOf(4)
         // index=3
        let result=array.splice(index)
        // result=4  
        // after splicing array =[1,2,3,5]  (splicing affects original array)
