Answer 1

you can make use of String.trim and Array.filter

arr = arr.filter(element => element.trim())

the trim method will remove starting and trailing whitespace, so the " " strings will be converted to "". Empty strings are considered falsy, so they will be removed by the filter function.

let arr = ["ruby","javascript","golang","dart","kotlin"," "," "," "," "];

console.log(arr.filter(e => e.trim()));
