How can I use slice in a loop?

function chunkArrayInGroups(arr, size) {
        let newArr =[];
         for (let i=0;i<arr.length;i++){

          console.log(arr.slice(arr[i],size+arr[i]))  
           
           newArr.push(arr.slice(arr[i],size+arr[i]));

                      //console.log(i);
         }
   
   //console.log(newArr)

}

chunkArrayInGroups(["a", "b", "c", "d"], 0);

I can only make the first cycle works, but how can I do the second one?.

function chunkArrayInGroups(arr, size) {

 let nweArr=[];         

          for (let i=0;i<arr.length;i++){

                      

            let newChunk=arr.slice(i,size-arr.length)

           i=size-arr.length

                 

                    console.log(newChunk)       

                                          

          }

                   

}

chunkArrayInGroups(["a", "b", "c", "d"], 2);

Yes, that represents the position where you want to start the cycle.

I still have to do these to get passed the challenge:
chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3) should return [[0, 1, 2], [3, 4, 5]] .

chunkArrayInGroups([0, 1, 2, 3, 4, 5], 4) should return [[0, 1, 2, 3], [4, 5]]

chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6], 3) should return [[0, 1, 2], [3, 4, 5], [6]] .

chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6, 7, 8], 4) should return [[0, 1, 2, 3], [4, 5, 6, 7], [8]]

function chunkArrayInGroups(arr, size) {
 let newArr=[];         
          
          for (let i=0;i<arr.length;i++){
                      
      
         let newChunk=arr.slice(i,i+size)

        newArr.push(newChunk)                        
      
         i=i+1;
          }
         console.log(newArr)
         // return newArr
}

chunkArrayInGroups(["a", "b", "c", "d"], 2);

I solved hte return issue, but how can I increment I while I am in a loop?

function chunkArrayInGroups(arr, size) {
 let newArr=[];         
          
          for (let i=0;i<arr.length;i++){
                      
      
         let newChunk=arr.slice(i,i+size)

        newArr.push(newChunk)                        
      
         i=i+1;

     
          }
        
        
         console.log(newArr)
          return newArr
}

chunkArrayInGroups(["a", "b", "c", "d"], 2);

It is done. Thanks!

function chunkArrayInGroups(arr, size) {
 let newArr=[];         
          
          for (let i=0;i<arr.length;i+=size){
                      
      
         let newChunk=arr.slice(i,i+size)

        newArr.push(newChunk)                        
      
         

     
          }
        
        
         console.log(newArr)
          return newArr
}

chunkArrayInGroups(["a", "b", "c", "d"], 2);
