handling exceptions for error wb.write()

[Fayris-develop]

Good afternoon. Is there some way to catch errors when writing is not possible?

I'll tell you right away that I'm a beginner. For some time I could not understand why my program crashes, and then I realized that I had an output file open. Is it possible to somehow prevent the program from crashing and let the user know about it?

This construction doesn't work:

try { wb.write('Result.xlsx'); } catch (ex) {
console.log("Close result file"); }

Environment (please complete the following information):

• OS: Windows 7
• excel4node Version: 1.7.2
