Frequently Asked Questions
What are template literals and how do they work?
Template literals use backticks (`) and allow embedded expressions with ${expression}. They support multi-line strings and make string interpolation cleaner than concatenation with + operators.
How do I split and join strings?
Use split() to convert a string into an array by splitting on a delimiter (like commas or spaces). Use join() to combine array elements into a string with a separator. These are inverse operations.
What are regular expressions and when should I use them?
Regular expressions (regex) are patterns for matching text. Use them for complex string searching, validation (like email formats), and text replacement. They are powerful but can be complex, so use them when simple string methods are insufficient.
