Given this array ar
and a list of separators
:
let ar = ["bestes", "haus", "Tiangua"];
const separators = [" ", ""];
How can I convert it into a string, while using as separator each value from the separators
array, instead of the usual commas?
Expected result:
res = ["bestes hausTiangua"]
This is my current implementation, but it would use the same separator only.
let kw = ar.join(',').replace.(/,/g, '/')
CodePudding user response:
You can do it in just one operation with the function Array.prototype.reduce:
ar.reduce((a, s, i) => a separators[i-1] s)
CodePudding user response:
Iterate over the array and shift from the separators every index.
const ar = ["bestes", "haus", "Tiangua"];
const separators = [" ", ""];
let str = ar[0];
for (let i = 1; i < ar.length; i ) {
str = separators.shift() ar[i];
}
console.log(str);
