Code duplication in javascript

Question

Is there any tool to detect duplicate code in JavaScript? I tried the "PMD Duplicate code detector", but it does not support the .js extension.

Answer 1

You can use JS Inspect to detect copied and structurally similar code, it also supports*.js

Installation

npm install -g jsinspect

Run

jsinspect -t 50 ./path/to/src

Answer 2

I would recommend looking at this stream (also on stackoverflow): Javascript source code analysis (in particular duplication check)

Answer 3

IDE . IntelliJ, IDE 2 :

• Inline: , .
• : Analyze- > Locate Duplicates.., .
