import {Boolean, False, True} from './Boolean'

/** Logical **`&&`** operator (behaves like the JS one)
 * @param B1 Left-hand side
 * @param B2 Right-hand side
 * @returns **`Boolean`**
 * @example
 * ```ts
 * import {B} from 'ts-toolbelt'
 *
 * type test0 = B.And<B.True, B.False>          // False
 * type test1 = B.And<B.True, B.True>           // True
 * type test2 = B.And<B.True | B.False, B.True> // Boolean
 * ```
