3. lastIndexOf( ) :

17. slice( ) :

• Extracting string from a string.
• takes two argument - (starting index, ending index) . ending index is not compulsory.

18. substring( ) :

• substring() is similar to slice() the difference is substring does not except negative indexes.
• If we give negative value then the character are counted from the 0th position.

19. substr( ) :

• 2 argument- (starting index, length of new string). 2nd argument can't be negative.

20. match( ) :

• The match() method searches a string for a match against a regular expression, and returns the matches, as an Array object.

21. padStart( ) :

• Add white spaces at the start of the string. Inside ( ) you need to give your total string length with starting whitespaces.
• whitespaces = length - string characters length

22. padEnd( ) :

• same as padStart( ) just here whitespaces will add at last.
• To recognize spaces , bellow in pic in comment at last added '|'

23. split( ) :

• Break string and convert it in array.
