how to use OR operator in nodejs

Question

I am trying to add an if condition; Idea is If I enter the input as print or text with 4 in it, else block should be called. if ((turnContext.activity.text.indexOf('print') == -1) || (turnContext.activity.text.indexOf('4') == -1)) Now, it goes into the if block as opposed to else.

You have to use: &&. Otherwise when the text is print, the text is not 4 entering the if block. if ((turnContext.activity.text.indexOf('print') == -1) && (turnContext.activity.text.indexOf('4') == -1)) { // not 4 nor print } else { // print or 4 }
