How can I split the \"arr\" into two arrays based on the \"point\" variabl

Sharing this convenience function that I ended up making after visiting this page.

function chunkArray(arr,n){
     var chunkLength = Math.max(arr.length/n ,1);
     var chunks = [];
     for (var i = 0; i < n; i++) {
         if(chunkLength*(i+1)<=arr.length)chunks.push(arr.slice(chunkLength*i, chunkLength*(i+1)));
     }
     return chunks; 
 }

Sample usage:

chunkArray([1,2,3,4,5,6],2);
//returns [[1,2,3],[4,5,6]]

chunkArray([1,2,3,4,5,6,7],2);
//returns [[1,2,3],[4,5,6,7]]

chunkArray([1,2,3,4,5,6],3);
//returns [[1,2],[3,4],[5,6]]

chunkArray([1,2,3,4,5,6,7,8],3);
//returns [[1,2],[3,4,5],[6,7,8]]

chunkArray([1,2,3,4,5,6,7,8],42);//over chunk
//returns [[1],[2],[3],[4],[5],[6],[7],[8]]
