console.log("a" >= "a"); // true
console.log("a" >= "3"); // true
console.log("5" >= 3); // true
console.log("3" >= 3); // true
console.log("3" >= 5); // false
console.log("hello" >= 5); // false
console.log(5 >= "hello"); // false
console.log(5 >= 3); // true console.log(3 >= 3); // true console.log(3 >= 5); // false
console.log(5n >= 3); // true console.log(3 >= 3n); // true console.log(3 >= 5n); // false
console.log(true >= false); // true console.log(true >= true); // true console.log(false >= true); // false console.log(true >= 0); // true console.log(true >= 1); // true console.log(null >= 0); // true console.log(1 >= null); // true console.log(undefined >= 3); // false console.log(3 >= undefined); // false console.log(3 >= NaN); // false console.log(NaN >= 3); // false
