1519+ 1520+ ## 46. The Hashtag Generator
1521+ 1522+ The marketing team is spending way too much time typing in hashtags. Let's help them with our own Hashtag Generator! Here's the deal:
1523+ 1524+ - It must start with a hashtag ` # `
1525+ - All words must have their first letter capitalized.
1526+ - If the final result is longer than 140 chars it must return ` false ` .
1527+ - If the input or the result is an empty string it must return ` false ` .
1528+ 1529+ ``` js
1530+ const generateHashtag = str => {
1531+ // Your solution
1532+ };
1533+ 1534+ console .log (generateHashtag (' JavaScript' // "#JavaScript"
1535+ console .log (generateHashtag (' Do We have A Hashtag' // "#DoWeHaveAHashtag"
1536+ console .log (generateHashtag (' ' // false
1537+ console .log (generateHashtag (' ' // false
1538+ console .log (generateHashtag (' a' repeat (140 ))); // false
1539+ console .log (generateHashtag (' a' repeat (139 ))); // #Aaaaaaa...
1540+ console .log (generateHashtag (' coding' + ' ' repeat (140 ) + ' for life' // "#CodingForLife")
1541+ console .log (generateHashtag (' ' repeat (200 ))); // false
1542+ ```
