/** * Returns the new version resulting from an increment by release type. * * `premajor`, `preminor` and `prepatch` will bump the version up to the next version, * based on the type, and will also add prerelease metadata. * * If called from a non-prerelease version, the `prerelease` will work the same as * `prepatch`. The patch version is incremented and then is made into a prerelease. If * the input version is already a prerelease it will simply increment the prerelease * metadata. * * If a prerelease identifier is specified without a number then a number will be added. * For example `pre` will result in `pre.0`. If the existing version already has a * prerelease with a number and its the same prerelease identifier then the number * will be incremented. If the identifier differs from the new identifier then the new * identifier is applied and the number is reset to `0`. * * If the input version has build metadata it will be preserved on the resulting version * unless a new build parameter is specified. Specifying `""` will unset existing build * metadata. * @param version The version to increment * @param release The type of increment to perform * @param prerelease The pre-release metadata of the new version * @param build The build metadata of the new version * @returns */export function increment(  version: SemVer,  release: ReleaseType,  prerelease?: string,  buildmetadata?: string,): SemVer {  const build = buildmetadata !== undefined    ? parseBuild(buildmetadata)    : version.build;
