From this javascript array
var test = [0, 1, 0, 1, 1, 1, 0, 0, 1, 0, 0, 0, 0, 1];
How can I do to get the result as displayed below. Thank you.
test = [[0],1,[0],1,1,1,[0,0],1,[0,0,0,0],1];
I have tried in many ways but I can’t find a solution
>Solution :
Here you go:
function group(a) {
let last = null, res = [];
for (let x of a)
if (x === 1)
res.push(last = x)
else if (Array.isArray(last))
last.push(x)
else
res.push(last = [x])
return res
}
let test = [0, 1, 0, 1, 1, 1, 0, 0, 1, 0, 0, 0, 0, 1];
console.log(group(test))
Can’t help wondering why you need such a thing though…
