Less than 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 strictly less than the value on the right-hand side of the operator.
Examples
Example: Numeric less than check
// Basic numeric less than check.
var x = 5;
var y = 4;
console.log(x < 4);
console.log(x < y);
Example: Comparing "apples" the "Apples"
// Basic string equality check. Case matters for string comparison.
var x = \"apples\";
var y = \"Apples\";
console.log(x < \"bananas\");
console.log(x < y);
Example: 2 is less than "12"?
// Numeric string to number conversion is automatic in App Lab.
var x = 2;
var y = \"12\";
if(x < y)
{
console.log(\"less\");
}
else
{
console.log(\"not less\");
}

Returns
Boolean true or false
Tips
- If you want to test if a value is less than OR equal, 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 < <= == > >= !=
