You can call   arr slice Math max arr length - 5  1     If you don t want to exclude the first element  use  arr slice Math max arr length - 5  0

Here is one I haven t seen that s even shorter  arr slice 1  slice -5   Run the code snippet below for proof of it doing what you want   x000D   x000D  var arr1    0  1  2  3  4  5  6  7   x000D    arr2    0  1  2  3   x000D   x000D  document body innerHTML    ARRAY 1      arr1 slice 1  slice -5      lt br  gt ARRAY 2      arr2 slice 1  slice -5   x000D   x000D   x000D    Another way to do it would be using lodash https   lodash com docs rest - that is of course if you don t mind having to load a huge javascript minified file if your trying to do it from your browser     slice   rest arr   -5

ES6 way   I use destructuring assignment for array to get first and remaining rest elements and then I ll take last five of the rest with slice method    x000D   x000D  const cutOffFirstAndLastFive    array    gt    x000D    const  first     rest    array  x000D    return rest slice -5   x000D    x000D   x000D  cutOffFirstAndLastFive  1  55  77  88    x000D   x000D  console log  x000D     Tests    x000D    JSON stringify cutOffFirstAndLastFive  1  55  77  88     x000D    JSON stringify cutOffFirstAndLastFive  1  55  77  88  99  22  33  44     x000D    JSON stringify cutOffFirstAndLastFive  1    x000D     x000D   x000D   x000D
