Question
What is the output of this code?let str="Hello world ! This is a wonderful day.";console.log(s.lastIndexof('w'));
Solution
The code will throw an error because s is not defined. It seems like you want to find the last index of 'w' in the string str. The correct code should be console.log(str.lastIndexOf('w'));.
However, without running the code, I can't provide the exact output. The lastIndexOf() method returns the position of the last occurrence of a specified value in a string. The string is searched from the end to the beginning, but returns the index from the beginning, at position 0. If the value is not found, the method returns -1.
