For example with substring() calls and concatenation (+):

var msg="Hello world this is a question";

var replaced=msg.substring(0,6)+"friends"+msg.substring(11);

console.log(replaced);

Method 1:

If you know the exact index you want to slice the string at, you should probably use javascript string.slice method like so:

var str = "Hello world!";

var part = str.slice(1, 5);

console.log(part); // "ello"

Method 2:

If you don't know the index, but you do know the string you want to replace, you can simply use string.replace method like so:

var input = "Hello world this is a question";

var result = input.replace("world", "friends");

console.log(result); // Hello friends this is a question
