javascript operator

Greater than or equal (>=)

View on MDN ↗

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

Interactive exampleOpen the canonical MDN source to run this embedded demo.
console.log(5 >= 3);
// Expected output: true

console.log(3 >= 3);
// Expected output: true

// Compare bigint to number
console.log(3n >= 5);
// Expected output: false

console.log("ab" >= "aa");
// Expected output: true

Syntax

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

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

String to number comparison

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

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

Number to Number comparison

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

Number to BigInt comparison

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

Comparing Boolean, null, undefined, NaN

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
