Identify unused variables in your javascript code.
## cli
```shell
$ unused /path/to/file.js
```
### --ignore-params
Comma separated list of function parameters to ignore during unused checks. You often want to know when you forgot to handle `err` or other parameters, but sometimes you have placeholders (`req`, `res`, etc) which you might want to ignore
```shell
$ unused /path/to/file.js --ignore-params req,res,_
```
## api
### unused(src)
> src is a javascript source string
Returns an array of objects specifying the name, location, and if the variable is a function parameter
```
{
name: 'foo',
loc: {
line: 1,
column: 1,
},
param: true || false
}
```
## install
```shell
npm install unused
