replace Examples

The general syntax for this method is:

stringName.replace(searchChar, replacementChar);
/*Given a search string searchChar and a replacement value
replacementChar, this method returns a copy of stringName with the 
first occurrence of searchChar replaced by replacementChar.*/

//Example
"carrot".replace("r", "t");

"Launch Code".replace(" ", "");
//catrot
//LaunchCode

//Example
/*Some email providers, including Gmail, allow users to put a . 
anywhere before the @ symbol. This means that 
[email protected] is thesame as [email protected].*/

//Remove the . before the @ symbol in an email address.

let input = "[email protected]";
let email = input.replace(".", "");
console.log(email);
//[email protected]

/*This example illustrates a common use case of replace, which is 
to remove a character by replacing it with the empty string.*/

/*Notice in the last example that if there is not a . before the
  @ symbol, the . that is part of the domain, launchcode.org would
  be inadvertently removed. In a real application, we would want to
  isolate the portion in front of @ using slice.*/
