Could anyone please let me know what is the best way to concat string in scala? We have +, concat() etc. Which one gives better performance? Thanks!

    + is just an alias for concat - Anyways, if you are going to contact only two that is fine, if you need to contact many and you know all of them then better use a string interpolator. Otherwise use a StringBuilder Commented Jan 13, 2022 at 16:05
