< (Less Than Operator)
Checks whether the left value is less than the right. Both operands must have the same type: int, float, string or bool. Strings use byte order, and false < true. An ordered comparison involving NaN returns false. See the ordering rules.
Example
let isLess = 3 < 5 // isLess = true
isLess = 3 < 5 // isLess = true
