# Greater than or equal (>=)

The greater than or equal (`>=`) operator returns `true` if the left operand is greater than or equal to the right operand, and `false` otherwise.

## Syntax

js

``````x >= y
``````

## Description

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)`, except for two cases where `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`.

## Examples

### String to string comparison

js

``````"a" >= "b"; // false
"a" >= "a"; // true
"a" >= "3"; // true
``````

### String to number comparison

js

``````"5" >= 3; // true
"3" >= 3; // true
"3" >= 5; // false

"hello" >= 5; // false
5 >= "hello"; // false
``````

### Number to Number comparison

js

``````5 >= 3; // true
3 >= 3; // true
3 >= 5; // false
``````

### Number to BigInt comparison

js

``````5n >= 3; // true
3 >= 3n; // true
3 >= 5n; // false
``````

### Comparing Boolean, null, undefined, NaN

js

``````true >= false; // true
true >= true; // true
false >= true; // false

true >= 0; // true
true >= 1; // true

null >= 0; // true
1 >= null; // true

undefined >= 3; // false
3 >= undefined; // false

3 >= NaN; // false
NaN >= 3; // false
