Question

I have a jsonArray something like this.

var json_array = [
    { "text": "id", "size": 4}, 
    { "text": "manifesto", "size": 4}, 
    { "text": "also", "size": 4}, 
    { "text": "leasing", "size": 4},
    { "text": "23", "size": 4}, 
    ...
];

I want to get first n elements of this json_array.

What will be the best way to do it? Apart from iterating them and having a counter to limit the size.

Answer 1

short hand (MDN Docu):

json_array.length = n;

somewhat longer (MDN Docu):

json_array.splice( n );
