I have an array called newresult which prints to the console like this:
const newresult = [
1, 0, 3, 0, 0, 0, 1, 2,
0, 0, 0, 1, 3, 0, 0, 0,
0, 0, 0, 2, 0, 0, 0, 3,
0, 0, 2
];
const sum = [newresult].reduce((partialSum, a) => partialSum + a, 0);
console.log(sum);
The array contents just printing as individual numbers.
Apologies, as I'm sure this is obvious, but what schoolboy error am I making here?
Also tried this:
const array1 = [newresult];
const initialValue = 0;
const sumWithInitial = array1.reduce(
(accumulator, currentValue) => accumulator + currentValue,
initialValue,
);
Same result:
01,0,3,0,0,0,1,2,0,0,0,1,3,0,0,0,0,0,0,2,0,0,0,3,0,0,2
Thank you
You are putting newresult
which is an array by itself inside another array , So inside reduce callback it is basically converting the array to a string and adding 0 to it
const newresult = [
1, 0, 3, 0, 0, 0, 1, 2,
0, 0, 0, 1, 3, 0, 0, 0,
0, 0, 0, 2, 0, 0, 0, 3,
0, 0, 2
]
const sum = newresult.reduce((partialSum, a) => partialSum + a, 0);
console.log(sum);
