My intention is to split an array using a separator and choose a limit of its splitting.
var arr = [89, 'sdf', 0, null, 0, true, 89, 0, 'sdf'];
var res = [];
while (arr.length) {
res.push(arr.splice(0, 2));
}
console.log(res)For example: If 0 is the separator and 2 is the limit
arr.split(0, 2)
[[89, 'sdf'], [null]] //output
You could use indexOf and splice like this:
var arr = [89, 'sdf', 0, null, 0, true, 89, 0, 'sdf'];
function splitArray(arr, seperator, count) {
let result = [],
copy = arr.slice(), // if you don't want to mutate the original array
counter = 0;
while(counter < count && copy.length > 0) {
const index = copy.indexOf(seperator);
if(index !== - 1) {
result.push(copy.splice(0, index));
copy.shift(); // remove the seperator
}
else result.push(copy.splice(0)) // add the remaining items
counter++
}
return result
}
console.log(splitArray(arr, 0, 2))
console.log(splitArray(arr, 0, 3))You could iterate the array and take a counter, which works as index for the result array and push the item into the result array of the counter.
function split(array, length, separator) {
var result = [],
count = 0,
i = 0;
while (count < length && i < array.length) {
if (array[i] === separator) {
count++;
i++;
continue;
}
result[count] = result[count] || [];
result[count].push(array[i++]);
}
return result;
}
console.log(split([89, 'sdf', 0, null, 0, true, 89, 0, 'sdf'], 2, 0));Version with indexOf and slice.
function split(array, length, separator) {
var result = [],
p,
i = 0;
while ((p = array.indexOf(separator, i)) !== -1 && result.length < length) {
result.push(array.slice(i, p));
i = p + 1;
}
if (result.length < length) result.push(array.slice(i));
return result;
}
console.log(split([89, 'sdf', 0, null, 0, true, 89, 0, 'sdf'], 2, 0));
console.log(split([89, 'sdf', 0, null, 0, true, 89, 0, 'sdf'], 5, 0));.as-console-wrapper { max-height: 100% !important; top: 0; }
you can use this one
var arrays = [], size = 2;
var arr = [89, 'sdf', 0, null, 0, true, 89, 0, 'sdf'];
while (arr.length > 0)
arrays.push(arr.splice(0, size));
nullbut remove0?[[89, "sdf"], [0, true]]?
