lets suppose i have string
var string = "$-20455.00"
I am trying to swap first two characters of a string. I was thinking to split it and make an array and then replacing it, but is there any other way? Also, I am not clear how can I achieve it using arrays? if I have to use arrays.
var string = "-$20455.00"
How can I achieve this?

replace() is an inbuilt method in JavaScript which is used to replace a part of the given string with some another string or a regular expression. The original string will remain unchanged. Parameters: Here the parameter A is regular expression and B is a string which will replace the content of the given string.
Use the replace() method to replace the first occurrence of a character in a string. The method takes a regular expression and a replacement string as parameters and returns a new string with one or more matches replaced.
Using 'str.replace() , we can replace a specific character. If we want to remove that specific character, replace that character with an empty string. The str. replace() method will replace all occurrences of the specific character mentioned.
You can use the replace function in Javascript.
var string = "$-20455.00"
string = string.replace(/^.{2}/g, 'rr');

You dont have to use arrays. Just do this
string[1] + string[0] + string.slice(2)
