API

stripVariationSelectors.version

A string representing the semantic version number.

stripVariationSelectors.reverse(string)

This function takes a string and returns the stripped version of that string, where any variation selectors have been removed.

Usage example

// Note: U+FE0E is a variation selector.
const string = '\u21D5\u25B6\uFE0E\u{1F600}'; // '⇕▶︎😀'
console.log(
  [...string].length
); // 4

const stripped = stripVariationSelectors(string);
console.log(
  [...string].length
); // 3

Unit tests & code coverage

After cloning this repository, run npm install to install the dependencies needed for strip-variation-selectors development and testing. You may want to install Istanbul globally using npm install istanbul -g.

Once that’s done, you can run the unit tests in Node using npm test or node tests/tests.js. To run the tests in Rhino, Ringo, Narwhal, and web browsers as well, use grunt test.

To generate the code coverage report, use grunt cover.
