From MDN :
The indexOf() method returns the index within the calling String object of the first occurrence of the specified value, The lastIndexOf() method returns the index within the calling String object of the last occurrence of the specified value
So the indexOf will return first occurrence of the value and the lastIndexOf will return the last occurence of the value.
Example (copied from MDN):
var anyString = "Brave new world";
var a = anyString.indexOf("w")); // result = 8
var b = anyString.lastIndexOf("w")); // result 10
Both of the method return -1 if the value is not found
