Comparison Operators

Use comparison operators in logical statements to determine equality or differences between variables or values.

You can use comparison operators in conditional statements to compare values ​​and perform actions based on the results.

JavaScript also includes conditional operators that assign values ​​to variables based on specific conditions.

If the variable age is smaller than 18, the value of the variable voteable is "Too young". Otherwise, the value of voteable will be "Old enough".

When comparing a string to a number, JavaScript converts the string to a number when comparing. Empty string is converted to 0. Non-numeric strings are converted to NaN. Always false.

The difference between JavaScript's "triple" comparison operator (===,! ==) and the double comparison operator (==,! =) Is that the double comparison operator implicitly converts an operand It is to compare. Instead of performing a type conversion using a triple operator comparison (that is, to equalize the operands, the values ​​are equal and the types must be the same). A lot of things can be said about this topic yet, but the short and important answer here is that strict use is a way to automatically implement the parsing and error handling of JavaScript code at run time. Otherwise code errors that are ignored or fail silently will generate an error or throw an exception. Generally speaking, this is a good habit.

We have already introduced the main comparison operators you may need to use. As usual, this is not a complete list, and there are several operators available (mainly used to replace file type tests), if necessary. This should be a useful reference for most comparisons you need to do when you start using it. In the next article I will explain another way to manipulate the program flow.

Our main technique is to identify a series of core operations based on encrypted data that underlies many classification protocols. We found that these operations are comparison, argmax, and inner product. We use an effective protocol for each of these by improving existing solutions (eg for comparison) or by building new solutions (eg for argmax). • The inputs and outputs of all building blocks are encrypted using additive homomorphic encryption. In addition, it provides a mechanism for switching from one encryption scheme to another. Intuitively, this makes the output of the building block the input to another building block.
