Thegreater than or equal (>=) operator returnstrue ifthe left operand is greater than or equal to the right operand, andfalseotherwise.

Try it

console.log(5 >= 3);// Expected output: trueconsole.log(3 >= 3);// Expected output: true// Compare bigint to numberconsole.log(3n >= 5);// Expected output: falseconsole.log("ab" >= "aa");// Expected output: true

Syntax

x >= y

Description

The operands are compared using the same algorithm as theLess than operator, with the result negated.x >= y is generally equivalent to!(x < y), except for two cases wherex >= y andx < y are bothfalse:

• 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 asyntax error when passed toBigInt()).
• If one of the operands gets converted toNaN. (For example, strings that cannot be converted to numbers, orundefined.)

x >= y is generally equivalent tox > y || x == y, except for a few cases:

• When one ofx ory isnull, and the other is something that's notnull and becomes 0 whencoerced to numeric (including0,0n,false,"","0",new Date(0), etc.):x >= y istrue, whilex > y || x == y isfalse.
• When one ofx ory isundefined, and the other is one ofnull orundefined:x >= y isfalse, whilex == y istrue.
• Whenx andy are the same object that becomesNaN after the first step ofLess than (such asnew Date(NaN)):x >= y isfalse, whilex == y istrue.
• Whenx andy are different objects that become the same value after the first step ofLess than:x >= y istrue, whilex > y || x == y isfalse.

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; // false5 >= "hello"; // false

Number to Number comparison

5 >= 3; // true3 >= 3; // true3 >= 5; // false

Number to BigInt comparison

5n >= 3; // true3 >= 3n; // true3 >= 5n; // false

Comparing Boolean, null, undefined, NaN

true >= false; // truetrue >= true; // truefalse >= true; // falsetrue >= 0; // truetrue >= 1; // truenull >= 0; // true1 >= null; // trueundefined >= 3; // false3 >= undefined; // false3 >= NaN; // falseNaN >= 3; // false
