Any language can solve similiar problems. Take this built-in php function: array_column array_column() returns the values from a single column of the input, identified by the column_key To perform the same in Javascript you either need to write something or find a package. There are many examples like this of build-in useful functionality. PHP allows you to do a lot with very little code which allows you to focus on a difficult problem rather than a difficult problem and how to shape it with whatever language. Keep learning javascript but don't try to do everything with it. Ignoring php, ruby or python on the backend will slow you down. Ignoring sql would be another mistake.
