Write a function that splits an array (first argument) into groups the length of size (second argument) and returns them as a multidimensional array.
Remember to use Read-Search-Ask if you get stuck. Try to pair program. Write your own code.
function chunk(arr, size) {
// Break it up.
return arr;
}
chunk(['a', 'b', 'c', 'd'], 2);
You need to take an array from the first parameter, and then make sub-arrays the size of the second parameter and return them inside a big array.
You will need two extra variables to store temp values and the new arrays.
You need to check if you already have enough elements or not and add them.
You will need to check if there is any elements to push before returning the final results.
var temp = [];
var result = [];
for (var a in arr) {
if (a % size !== size - 1)
temp.push(arr[a]);
else {
temp.push(arr[a]);
result.push(temp);
temp = [];
}
}
if (temp.length !== 0)
result.push(temp);
return result;
}
-
Create a temp variable and an results variable.
-
For every element in the array:
- if the index of the element is even then add the element temp variable.
- Otherwise it means that we already have an element and should add the element and flush temp into results.
-
Outside the loop, we check if temp is empty and return accordingly.
