Decaffeinate spec/link-spec

[GuilleW]

Since I work on many files, I edit package.json to add useful shortcut to avoid misspelt filename.

    "test-decaff": "npx coffee --compile --output spec spec/${npm_config_name}.coffee",
    "test-coffee": "jasmine-focused --captureExceptions --coffee spec/${npm_config_name}.coffee",
    "test-js": "jasmine-focused --captureExceptions spec/${npm_config_name}.js"

Steps to reproduce decaffeination (guidelines):

• Check package.json for coffee-script version
  • version: 1.12.7
• Decaffeination with official Coffee program
  • npx coffee --compile --output spec spec/link-spec.coffee
  • (or my shortcut: ./bin/npm run test-decaff --name=link-spec)
• Quality of Decaffeination
  • Replace var with const and let if it's possible.
  • Replace Nested Ternary Operators with if statements.
  • Remove return when it's not needed.
  • Remove Result Arrays when they are not needed.
  • Replace for loops with for-of loops.
  • Use Arrow Functions to write functions in a single line when it's possible.
  • Remove unneeded ref variables.
  • Remove do blocks and use let or const instead.
  • Tests and assertions should be the same and success like in coffee file

Test from coffee and JS should output same successful result :

From coffee

$ jasmine-focused --captureExceptions --coffee spec/link-spec.coffee
// or my shortcut $ `./bin/npm run test-coffee --name=link-spec`
> 8 tests, 24 assertions, 0 failures, 0 skipped

to js

$ jasmine-focused --captureExceptions spec/link-spec.js
// or my shortcut $ `./bin/npm run test-js --name=link-spec`
> 8 tests, 24 assertions, 0 failures, 0 skipped
