I am having this issue replacing element from first array by another element of second array.
For exapmle if I have one array haiving some empty values and string like this:
let array_1 = [empty, 'Connected', empty, 'Connected', 'Connected'];
And another new array will be like this:
let array_2 = [empty, 'Updated'];
So, New updated array with replaced element will look like this:
newArray = [empty, 'Updated', empty, 'Connected', 'Connected'];
I tried with for loop and by using findIndexof, but could not replace the element with exact index address.
One of them which worked for me partially is:
console.log(Object.values(...array_1, ...array_2));
Out of above line is just one array with one element, not reast of element from array_1
:
['Updated']
But it seems like Obejct.values()
does not work with element generated as a empty
.
Any possible solution on this would be great!

If I understood it properly you can solve it by using map function like this:
let array_1 = [undefined, "Connected", undefined, "Connected", "Connected"];
let array_2 = [undefined, "Updated"];
const res = array_1.map((val, idx) => {
return array_2[idx] || val;
});
console.log(res);
