--description--

Given a string that may include some italic text in Markdown, return the equivalent HTML string.

• Italic text in Markdown is any text that starts and ends with a single asterisk (*) or a single underscore (_).
• There cannot be any spaces between the text and the asterisk or underscore, but there can be spaces in the text itself.
• Convert all italic occurrences to HTML i tags and return the string.

For example, given "*This is italic*", return "<i>This is italic</i>".

Note: The console may not display HTML tags in strings when logging messages. Check the browser console to see logs with tags included.

--hints--

parseItalics("*This is italic*") should return "<i>This is italic</i>".

assert.equal(parseItalics("*This is italic*"), "<i>This is italic</i>");

parseItalics("_This is also italic_") should return "<i>This is also italic</i>".

assert.equal(parseItalics("_This is also italic_"), "<i>This is also italic</i>");

parseItalics("*This is not italic *") should return "*This is not italic *".

assert.equal(parseItalics("*This is not italic *"), "*This is not italic *");

parseItalics("_ This is also not italic_") should return "_ This is also not italic_".

assert.equal(parseItalics("_ This is also not italic_"), "_ This is also not italic_");

parseItalics("The *quick* brown fox _jumps_ over the *lazy* dog.") should return "The <i>quick</i> brown fox <i>jumps</i> over the <i>lazy</i> dog.".

assert.equal(parseItalics("The *quick* brown fox _jumps_ over the *lazy* dog."), "The <i>quick</i> brown fox <i>jumps</i> over the <i>lazy</i> dog.");
