Practice 01

Create a simple character counter for Tweets.

Ask the user to type a Tweet
Count the characters
Show how many characters are left

Note that the maximum length for a Tweet is 280 characters.

Test Data:

Data Set	Tweet Content	Character Count	Remaining Characters
Data 1	Just finished reading an amazing article on space exploration! Can't believe how far we've come. #science #NASA #space	118	162
Data 2	Excited to attend the upcoming tech conference this weekend! Looking forward to insightful talks, hands-on workshops, and connecting with fellow enthusiasts. So much innovation packed into a few days—can’t wait! #TechConference #Innovation #Networking	251	29
Data 3	This is a test Tweet designed specifically to exceed the maximum character limit of 280 characters. It contains a bunch of filler text to make sure we go well beyond the standard length allowed. Keep typing, keep typing, adding more words just to hit that threshold. This sentence should do the trick!	301	-21

Solution

Code:

var tweet = prompt("Compose a tweet: ");

var tweetCount = tweet.length 

alert("You have written "
      + tweetCount 
      + " characters. You have "
      + (280 - tweetCount) 
      + " characters remaining."
)
