semver compare

Question

Please implement a function to compare 2 semver strings.

compare('12.1.0', '12.0.9')
// 1, meaning first one is greater

compare('12.1.0', '12.1.2')
// -1, meaning latter one is greater

compare('5.0.1', '5.0.1')
// 0, meaning they are equal.

/**
 * @param {string} v1
 * @param {string} v2
 * @returns 0 | 1 | -1
 */
function compare(v1, v2) {
  // your code here
