Javascript empty an existing array

A couple methods on how to empty an array in Javascript

• New empty array references remain unchanged

  Be aware that if you had any references to my_array they'll remain unchanged as you would be pointing my_array to a newly created one.

  my_array = []; // other_array is still [1, 2, 3]Copy code to the clipboard

• Setting array.length to 0

  Be aware that as we're updating the value, all references to my_array will still point to the same changed array.

  my_array.length = 0; // other_array is now empty []Copy code to the clipboard

• Array splice() method

  Be aware that as we're updating the value, all references to my_array will still point to the same changed array.

  my_array.splice(0, my_array.length); \n // other_array is now empty []Copy code to the clipboard

• Lodash's remove() method

  Be aware that as we're updating the value, all references to my_array will still point to the same changed array.

  _.remove(my_array, undefined); \n // other_array is now empty []Copy code to the clipboard
