JavaScript Less Than or Equal(<=) to the operator is used to compare two operands and return true if the left operand is smaller or equal to the right operand. The algorithm used for the comparison is the same as that of less than operator but equal condition is also checked
Syntax:
a<=b
Example 1: In this example, we will compare String, Number, and Boolean using Less Than or Equal Operator.
Javascript
console.log("3"<=2); console.log("2"<=3); console.log(true<=false); console.log("3"<="2"); console.log(3<=2); |
Output: The values are converted to the same data type and then compared. Here true is treated as one and false as 0. Therefore false is less than true.
false true false false false
Example 2: In this example, we will use the greater than or equal operator on BigInt and other data types.
Javascript
console.log(2n<=2); console.log(5n<=4); console.log(undefined<=null); console.log(null<=undefined) |
Output: 2n is equal to 2 as the comparison is made after type conversion
true false false false
