String replace multiple characters with an asterisk in JavaScript
We are required to write a JavaScript function that takes in a string as the first argument and an array of numbers. Our function should replace all the characters in the string at indices that are specified by the array elements taken as the second argument with an asterisk.
Example
The code for this will be −
const str = "Lorem ipsum dolor sit amet consectetur adipiscing elit";
const arr = [4, 7, 9, 12, 15];
const replceWithAsterisk = (str, indices) => {
let res = '';
res = indices.reduce((acc, val) => {
acc[val] = '*';
return acc;
}, str.split('')).join('');
return res;
};
console.log(replceWithAsterisk(str, arr));Output
The output in the console −
Lore* i*s*m *ol*r sit amet consectetur adipiscing elit
