// with preprelease versions. We add '^' to ensure that we are always
|
||
|
|
// comparing ranges with ranges, which sidesteps this logic.
|
||
|
|
// For example:
|
||
|
|
//
|
||
|
|
// semver.intersects(`<7.0.1`, "7.0.0-beta.0") // false - surprising
|
||

|
// semver.intersects(`<7.0.1`, "^7.0.0-beta.0") // true - expected

//
|

// This is because the first falls back to
|
||
|
|
//
|
||
|
|
// semver.satisfies("7.0.0-beta.0", `<7.0.1`) // false - surprising
|
||
|
|
//
|
||
|
|
// and this fails because a prerelease version can only satisfy a range
|
||
|
|
// if it is a prerelease within the same major/minor/patch range.
|
||

|
//
|

// Note: If this is found to have issues, please also revist the logic in
|
||
|
|
// babel-core's availableHelper() API.
