JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables The Variable Challenge Solution

Need help understanding the usage of commas and quotation marks used here in the lesson

Here ------> "<h2>There once was a " + adjective; var verb = prompt('Please type a verb'); var noun = prompt('Please type a noun'); alert("All done. Ready for the message?"); sentence += ' programmer who wanted to use JavaScript to ' + verb; sentence += ' the ' + noun + ' <-----------Here document.write(sentence);

I understood you can interchange “ and ‘ (commas and quotation marks) as shown in the video lesson, right? Although to apply best practice you stay consistent, right? If so, I put quotation marks and it doesn’t run my code. What am I not getting about mixing commas and quotation marks used in the video versus me putting quotation marks at the end to be consistent?

Commas ( , ) cannot be substituted for quotes ( " ), but apostrophes can ( ' :point_left: also known as a "single quote").

And the code shown above is missing part of the last literal string. There should be something (perhaps just a period) and another apostrophe, and ideally a semicolon all before the "document.write" statement:

sentence += ' the ' + noun + '       // incomplete, unbalanced 's
sentence += ' the ' + noun + '.';    // fixed
