Doubt in lastIndexOf

#1

not got it completely

if i write 4 in it like lastIndexOf(‘ab’, 4)
then will leave 0 to 4 characters from last?

and also does it start searching from the last?

#2

No it will read from starting only not from the end.
Also the 2nd argument is the position till where u want to check the presence of that string i.e

“I am Samarth vohra”.lastIndexOf(‘sam’ , 8)

Here it will check the last tym sam was being encountered to 8 positions where 8 is also included and returns the index from starting itself

Hope this clears your query
Happy learning :blush:
