I have an array of strings. Some of the strings within this array have a pipe character. I would like to split the strings by "|" and store all the unique values into a new array.
What would be an efficient way to get a temporary array with all the splited values in it, without using poor performance loops?
Once I have the temporary array with all the splited values in it, I plan de remove all duplicates like this : var result = [...new Set(result)]
var arr = ["A|B|C","B|A","E|A|D","F"]
// result does not have to be sorted
var expectedResult = ["A","B","C","D","E","F"]
.join('|') array as a string with pipes between all letters, then .split('|') by the pipe and then remove dupes with Set()
let data = ["A|B|C", "B|A", "E|A|D", "F"];
console.log([...new Set(data.join('|').split('|'))]);I would go with
const result = arr.map(item => item.split("|")).flat();
const deduped = [...new Set(result)]
