javascript help needed

Post by robbaust »

Hi please could someone point me in the right direction

I have to do a piece of javascript that asks the user to type in a sentence then print out each word on a separate line then count out a given letter (say the letter A) and display how many times that letter appears in that word the number also needs to appear beside that word so say apple a day keeps the doctor away would print out

apple 1
a 1
day 1
keeps 0
the 0
doctor 0
away 2

I hope this makes sense

here is my code

cheers rob

You can remove
this.phrase = phrase 
since you don't actually ever use it.

That looks like it is the problem too, since there is no ; at the end of that line it would be causeing a syntax error.
