![]() Ok, now, for the end, I’m gonna push your logic one step further and I’m gonna try to help you understand that programming is all about abstraction. Collaborate outside of code Explore All features. Boolean operators act on sets - groups of records conta. The Boolean operators, AND, OR, and NOT, help you construct a logical search. Learn how to identify if using it is a wise choice, many times using the classic if statement is better. There are two sorts of logical operators: those that accept and return vectors of any length (elementwise operators:, , &, xor() ) and those that only. Boolean logic (named after mathematician George Boole) is a system of logic to designed to yield optimal search results. Don’t over-complicate just for the sake of writing ternary operators.Use parenthesis to differentiate arguments when they look confusing.Notice how in the example we were analyzing before I made use of parenthesis around the conditional argument, the reason why I did it is to avoid the visual confusion of having the operators = and >= too close together, so, as a general rule, if you’re using operators that make a statement uncomfortable to read then use parenthesis.Recommendations: When you get used to writing code with ternary operators it’s very easy to write bad code just because “it has fewer lines of code”, to avoid making these mistakes I recommend you to: In the explanation above I didn’t mention that the Ternary Operator’s implementation is cleaner (and most importantly, it makes you feel badass the first times you use it). Else Insert code to execute if newCustomer False. VB Copy If newCustomer True Then Insert code to execute if newCustomer True. The simplest is the direct comparison of the value of a Boolean variable to a Boolean literal, as shown in the following example. ![]() ![]() ![]() Less redundant, look at the if’s statement case again and check how many times do you see the canDrive variable named?, 3 times right?, now look at the Ternary Operator implementation, just once… Boolean expressions can take several forms.in the first example using the if statement we had to declare canDrive using let because we needed to console.log the value out of the if’s block-scope (Don’t know what block-scope means?, read this article where I explain it better), in the Ternary Operator’s case we were able to use const because the variable is not limited by any block, which means we have more flexibility.Based on the expression evaluation, it returns the value. Let me explain why this is so good, I can think of at least 3 things right away: These boolean operators basically execute the code to check whether the expression value is true or not. Const canDrive = age >= 18 ? 'Yes' : 'No' // parenthesis are optional ![]()
