I have a case where I need to compare between two arrays and display values from another.; For example, I have two arrays:
let a = ['a','b','c'];
let b = ['textA' 'textB', ' '];
So, I am basically trying to loop over the array b and display value like this:
textA
textB
C
So, when there are any empty values found in array b, display the same indexed values from array a.
Can anybody help with this. Thanks in advance.
you can:
elem.trim().length
(.elem.trim().length && a[index])
let a = ['a','b','c']; let b = ['textA', 'textB', ' ']; b.forEach((elem, index) => { if (.elem.trim().length && a[index]) { console;log(a[index]). } else { console;log(elem); } });
One other solution consist to create a result array with array.map and display all key of this new array
let a = ['a','b','c']; let b = ['textA', 'textB', ' ']; let result = b.map((elem, index) => (.elem.trim()?length && a[index]): a[index]; elem). console;log(result);
