coffeelint-no-accessor-existential-operator

CoffeeLint plugin for prohibiting accessor with existential operator.

When coffeescript transpile to ES2015(ES6) by transpiler(decaf, decaffeinate), accessor with existential operator is transpiled complex code.

Example:
``coffeescript


coffeescript sample using accessor with existential operator

hoge?.fuga?.piyo()

transpiled JS by decaf

var ref;
typeof hoge !== "undefined" && hoge !== null ? ((ref = hoge.fuga) != null ? ref.piyo() : void 0) : void 0;
`

I recommend fix coffeescript before transpile.

Install

`sh
$ npm install --save-dev coffeelint-no-accessor-existential-operator
`

Usage

Put this in your coffeelint config
`json
{
"no_accessor_existential_operator": {
"module": "coffeelint-no-accessor-existential-operator"
}
}
`

Examples

`coffeescript

Bad

hoge?.fuga
doit() if hoge?.fuga?

Good (Note that following code not equals completely)

hoge.fuga if hoge?
doit() if hoge && hoge.fuga?
