How to use Array reduce() In Javascript
To iterate over characters of a string using `reduce()`, convert the string to an array of characters with split(”), then use reduce() to concatenate each character to the accumulator, resulting in the complete string.
Example:
const str = "w3wiki";
const result = Array.prototype.reduce.call(str, (acc, char) => {
console.log(char);
return acc + char;
}, '');
Output
G e e k s f o r G e e k s
