		## Usage

		### `removeConst` (default)

		Removes the `const` keyword to use regular `enum`.
		Can be used in a slower dev build to allow `const`, while prod still uses `tsc`.
		See [babel#6476](https://github.com/babel/babel/issues/6476).

		```ts
		// Before:
		const enum MyEnum {
		A = 1,
		B = A,
		C,
		D = C,
		E = 1,
		F,
		G = A * E,
		H = A B C,
		I = A << 20
		}

		// After:
		enum MyEnum {
		A = 1,
		B = A,
		C,
		D = C,
		E = 1,
		F,
		G = A * E,
		H = A B C,
		I = A << 20
		}
		```

		`.babelrc`
		```json
		{
		"plugins": [
		"const-enum"
		]
		}
		```

		Or Explicitly:

		`.babelrc`
		```json
		{
		"plugins": [
		[
		"const-enum",
		{
		"transform": "removeConst"
		}
		]
		]
		}
		```

		### `constObject`

		Transforms into a `const` object literal.
		Can be further compressed using Uglify/Terser to inline `enum` access.
		See [babel#8741](https://github.com/babel/babel/issues/8741).

		```ts
		// Before:
		const enum MyEnum {
		A = 1,
		B = A,
		C,
		D = C,
		E = 1,
		F,
		G = A * E,
		H = A B C,
		I = A << 20
		}

		// After:
		const MyEnum = {
		A: 1,
		B: 1,
		C: 2,
		D: 2,
		E: 1,
		F: 2,
		G: 1,
		H: 1,
		I: 1048576
		};
		```

		`.babelrc`
		```json
		{
		"plugins": [
		[
		"const-enum",
		{
		"transform": "constObject"
		}
		]
		]
		}
		```
