splice ( 0, 1 ) ) // : deletes 1 element starting at index 0 console. log (myArray ) // const secondArray = console. Here, cake is modified and reduces in size. log (cake ) // (5) let yourDoublePieceOfCake = cake. If items to insert such as itemToInsert1 are omitted, elements are only removed.Ĭonst cake = let myPieceOfCake = cake.If deleteCountis omitted,the elements until the end of array are removed.An array is returned with the deleted items.Splice is the real world cake "slice" arr. In addition to removing elements, splice is also used to add elements. Splice does operations in place, which means it modifies exisiting array. log (infiniteCake ) //Īs you see, inifinteCake is unmodified. slice ( 0, 1 ) // let yourDoublePieceOfCake = infiniteCake. If start is -ve, the elements are counted from the end.Ĭonst infiniteCake = let myPieceOfCake = infiniteCake.If end is omitted, end becomes the end (last element) of array.A new array is returned and the original array is unmodified.Like the name suggests, it is used to slice elements out of an array, but unlike slicing a cake, slicing an array does not cut the actual array, but keeps it unmodified (infinite cake!). It is used to slice an array from the start point to end point, excluding end.
So I am hoping this trick will help me and you in the future - S (p) lice = Slice + (p) => Slice + in (p) lace This could be translated to "how to not get confused between splice and slice" because, I can never remember the difference between the two.
