const { A, B, C } = Enum.Numeric({ startIndex: 5, step: 2 }); console.log(A); // Outputs: 5 console.log(B); // Outputs: 7 import Enum from "enum-xyz"; const { blue, red } = Enum.Symbol(); console.log(blue); // Outputs: Symbol(blue) global: Create a global symbol using Symbol.for().
const { blueGlobal } = Enum.Symbol({ global: true }); console.log(blueGlobal); // Outputs: Symbol.for('blueGlobal')
