How To Create Dynamic Arrays Varaibles in Javascript

Question

Can you please let me know if it is possible to create dynamically sets of arrays in JS? I tried some thing like this but didn't work

for (i = 0; i < 3; i++) { 
 var item[i] = [];
}
item1.push(1);
console.log(item1);

• Rayon: Dynamic array and Dynamic variables are different. Multidimensional array will be the solution for your problem.. You can not create dynamic variables

• krato: I don't quite get what you are trying to achieve, are you creating dynamic 2D arrays?

Answer 1

You're almost there. Assuming you're trying to create a two dimensional array (an array of arrays), you just have to declare the top level array and then reference the first level array with [x] array syntax like this:

var items = [];
for (i = 0; i < 3; i++) { 
 items[i] = [];
}
// Here items is an array of arrays where each first level array entry
// is an empty array. You can then put things into those empty arrays
// You can reference the first level array here
items[1].push(1);
items[1].push(2);
console.log(items[1]); // [1,2]
