Why does a javascript RegExp created by /…/ work but the same created via “new RegExp” does not?

Question

I\'m confused as to what the difference here is and why one works and the other does not. Can someone explain this?

//The string to search through
var str =          


        

Answer 1

In order to get the equivalent of /(\/\*)/g, you want new RegExp("(\\/\\*)", "g").
