Very cool! In that example though... where's the array? And don't backticks do string interpolation?

- sime2009 10y agoBackticks by themselves will do string interpolation. But backticks with a function name in front will do something a bit different. In this case 'sql.query' is a function and the JS will pass it an array which represents the contents of the backtick string. There the function can do what it likes and return a result. 'sql.query' builds a proper (and safe!) SQL query and executes it. The backtick feature in ES2015 is really cool and allows for some great DSL type features.
- tonyarkles 10y agoNeat! Thanks for the awesome explanation!
