substring method

• Pass two arguments
  1. The first argument is the beginning substring's index
  2. The second argument is the location after the substring
  For example,

  var myName = "Chu, Valerie Y";
  var Last = myName.substring(0,3); //Last will have "Chu".
  

• Pass one argument:
  The argument is the beginning substring's index.
  The substring will be taken to the end of the string.
  For example,

  var myName = "Chu, Valerie Y";
  var Name = myName.substring(5); // Name will have "Valerie Y"
  

search method

1. Find the location of the comma to identify the last name.
2. Use substring to extract the last name once you have the location of the comma
3. Find the first blank space to identify the beginning of the first name.
4. Extract the first name and the middle name together to save in a new variable.
5. Use the new variable to identify another space location in order to get first name
