I'm trying to chunk my array into 3 using this code
var a = ["a", "b", "c", "d", "e", "f", "g"];
let chunk;
while (a.length > 0) {
chunk = a.splice(0, 3);
console.log(chunk);
}but how can I get a result something like these
var array1 = ["a", "d", "g"];
var array2 = ["b", "e"];
var array3 = ["c", "f"];
const a = ["a", "b", "c", "d", "e", "f", "g"];
const numberOfArrays = 3;
let arrays = Array.apply(null, Array(numberOfArrays)).map(it=>[])
a.forEach((value,i)=>{
arrays[(i%numberOfArrays)].push(value);
})
console.log(arrays)
.map(it=>[]) do, please?
Array(3).fill([]); and got same [[],[],[]]. Afterwards i run your foreach: a.forEach((value,i)=>{ arrays[(i%3)].push(value); }) But i got completly wrong result. I dont understand it.Value to fill the array with. (Note all elements in the array will be this exact value.) arrays and object are copied by ref in js all the elements in chunks as same ref to the array you pass to fill function, with map each cluser create new arrayIterate over a and put the first element into array1, the second element into array2, the third element into array3, ...
const a = ["a", "b", "c", "d", "e", "f", "g"];
const [array1, array2, array3] = a.reduce((acc, el, idx) => {
acc[idx % 3].push(el);
return acc;
}, [[], [], []]);
console.log(array1);
console.log(array2);
console.log(array3);
aand put the first element intoarray1, the second element intoarray2, the third element intoarray3, ... The remainder operator could be helpful.
