The operands are compared using the same algorithm as the Less than operator, with the result negated. x >= y is generally equivalent to !(x = y and x < y are both false If one of the operands gets converted to a BigInt, while the other gets converted to a string that cannot be converted to a BigInt value (it throws a syntax error when passed to BigInt()). If one of the operands gets converted to NaN. (For example, strings that cannot be converted to numbers, or undefined.) x >= y is generally equivalent to x > y || x == y, except for a few cases When one of x or y is null, and the other is something that's not null and becomes 0 when coerced to numeric (including 0, 0n, false, "", "0", new Date(0), etc.): x >= y is true, while x > y || x == y is false. When one of x or y is undefined, and the other is one of null or undefined: x >= y is false, while x == y is true. When x and y are the same object that becomes NaN after the first step of Less than (such as new Date(NaN)): x >= y is false, while x == y is true. When x and y are different objects that become the same value after the first step of Less than: x >= y is true, while x > y || x == y is false.
