This code provides utilities for handling and searching through operator data in JavaScript (ES6).

// Sample operator data for demonstration purposes
const operators = {
    '+': { name: '_ADD', infix: { name: '_PLUS' }, prefix: null },
    '-': { name: '_SUB', infix: { name: '_MINUS' }, prefix: { name: '_NEGATE' } },
    '*': { name: '_MUL', infix: null, prefix: null },
    '/': { name: '_DIV', infix: null, prefix: null },
    // ... potentially other operators ...
};

// Create a set of all operator names
const operatorNamesSet = new Set(
    Object.values(operators)
        .flatMap(({name, infix, prefix}) => [name, infix?.name, prefix?.name])
        .filter(Boolean)
);

console.log(operatorNamesSet);  // Output: Set { '_ADD', '_PLUS', '_SUB', '_MINUS', '_NEGATE', '_MUL', '_DIV' }

// Utility function to find an operator object by its name
const findOperatorObject = (name) =>
    Object.entries(operators).find(
        ([, value]) => value.name === name || value.infix?.name === name || value.prefix?.name === name
    );

const [operatorSymbol, operatorObject] = findOperatorObject('_ADD') || [];
console.log(operatorSymbol, operatorObject);  // Output: '+' { name: '_ADD', infix: { name: '_PLUS' }, prefix: null }

// Log all operator entries
console.log(Object.entries(operators));
