Less than or equal operator
Category:Math
Your apps will sometimes need to check the relative size of two values, and then possibly perform some specific action using an if, if-else, or while block. < returns true if the value on the left-hand side of the opertor is less than or equal to the value on the right-hand side of the operator.
Examples
Example: Less Than Or Equal
// Basic numeric less than or equal to check.
var x = 5;
var y = 4;
console.log(x <= 5);
console.log(x <= 6);
console.log(x <= y);
Example: Comparing apples To Apples
Basic string less than or equal to check. Case matters for string comparison.
// Basic string less than or equal to check. Case matters for string comparison.
var x = "apples";
var y = "Apples";
console.log(x <= "apples");
console.log(x <= "bananas");
console.log(x <= y);
Syntax

Parameters
| Name | Type | Required? | Description |

| ___ | any | The operands can be a number/string/boolean, or a variable containing a number/string/boolean, or the number/string/boolean returned by a function, or the number/string/boolean result of the evaluation of an expression. |
Returns
Boolean true or false
Tips
- If you want to test if a value is less than, you can use the < operator.
- JavaScript will automatically perform type conversion for you when comparing two values (e.g. the integer 5 will register as equivalent to the string "5").
- When comparing two strings, JavaScript will compare them alphabetically based on character by character comparison left to right. All the upper case letters come before the lower case letters.
- Comparison operators include < <= == > >= !=
