#### isBunModule(moduleName, bunVersion?)

Checks if a specifier is a Bun module.

``typescript
import { isBunModule } from "is-bun-module";
isBunModule("bun"); // true
isBunModule("bun:test", "1.0.0"); // true
isBunModule("notBunModule"); // false
`

#### isBunImplementedNodeModule(moduleName, bunVersion?)

Checks if a specifier is a Node module implemented in Bun.

`typescript
import { isBunImplementedNodeModule } from "is-bun-module";
isBunImplementedNodeModule("fs"); // true
isBunImplementedNodeModule("node:fs"); // true
isBunImplementedNodeModule("node:notNodeModule"); // false
isBunImplementedNodeModule("node:http2", "1.0.0"); // false, added in 1.0.13
`

#### isBunBuiltin(moduleName, bunVersion?)

Checks if a specifier is either a Bun module or a Node.js module implemented in Bun.

`typescript
import { isBunBuiltin } from "is-bun-module";
isBunBuiltin("bun"); // true
isBunBuiltin("fs"); // true
isBunBuiltin("notBunModule"); // false
`

$3

#### getBunModules(bunVersion?)

Returns an array of all Bun modules available in the specified version.

`typescript
import { getBunModules } from "is-bun-module";
getBunModules(); // ["bun", "bun:ffi", ...]
getBunModules("1.0.0"); // Returns modules available in version 1.0.0
`

#### getBunImplementedNodeModules(bunVersion?)

Returns an array of all Node.js modules implemented in Bun for the specified version.

`typescript
import { getBunImplementedNodeModules } from "is-bun-module";
getBunImplementedNodeModules(); // ["fs", "path", ...]
getBunImplementedNodeModules("1.0.0"); // Returns implemented Node.js modules in version 1.0.0
`

#### getBunBuiltinModules(bunVersion?)

Returns an array of all builtin modules (both Bun modules and implemented Node.js modules).

`typescript
import { getBunBuiltinModules } from "is-bun-module";
getBunBuiltinModules(); // ["bun", "bun:ffi", "fs", "path", ...]
`
