Coverage increased (+0.005%) to 99.286% when pulling 2c0a9dc on samikarak:master into 185d2f2 on remarkablemark:master.

@remarkablemark I updated the pull request like described in the previous one, would you mind merging your current changes on master branch into it ?

The previous PR somehow got deleted after a rebase. I just commented there, that the regex you proposed did not work for custom styles containing dashes in between e.g '--custom-style' would get transformed into '-CustomStyle' since the regex would return false.

// regex that matches custom property or no hyphen
var CUSTOM_PROPERTY_OR_NO_HYPHEN_REGEX = /^--[a-zA-Z]+$|^[^-]+$/;

function camelCase(string) {
  // ...

  if (CUSTOM_PROPERTY_OR_NO_HYPHEN_REGEX.test(string)) {
    return string;
  }

  // ...

Now I just replaced string.startsWith('--') with string.indexOf('--') === 0.

function camelCase(string) {
  // ...

  // customStyle or no hyphen found
  if (string.indexOf('--') === 0 || string.indexOf('-') === -1) {
    return string;
  }

  // ...
