@News247Ug This seems related to Ronaldo long term girlfriend relationship instead of marriage 🤔

Footballer Achraf Hakimi's wife filed for divorce and demanded half of his property. She was however informed by court that her "Millionaire' husband owns nothing as all his property is registered under his mother's names. Hakimi receives €1 Million from PSG monthly but 80% of this is deposited in his mother Mrs. Fatima's account. He has no property, cars, houses, Jewelry or even clothes in his name. Anytime, he wants anything, he asks his mother who buys it for him. #News247

@haider1 The code would break when you declare variable with the same name twice hence there's no result. The first a variable was declared in the global scope and all global scope variable can be accessed anywhere in the code hence preventing the redeclaring of the variable.

Can you guess the output with explanation ❓

@Dominus_Kelvin Got it

Alright! Thank you for playing 😁 So at first glance, one may think "Well JavaScript will hoist the function of course because functions are hoisted(or variables declared with var are hoisted)" But if you look closely, the greeting function was defined as a function expression, not a formal function declaration. You see only formal function declarations are hoisted And this hoisting has nothing to do with the var keyword in this context (using const or let won't change the output of this code. We are dealing with Function hoisting here not variable hoisting) So that's the first lesson: only formal function declarations are hoisted which means you can invoke them before the line they are defined. By formal function declaration, I mean functions that are defined with the function keyword first and not assigned to a variable like the greet function below. So this is the output of calling greeting 👇🏾 This makes sense since we have seen that function expressions are not hoisted so the greeting identifier will have the value of undefined( you can do typeof greeting to verify that) So the code crashes because we were literally calling undefined() and since undefined is not a function(obviously), we get a TypeError since we can't call a value of type undefined as we call a function. To recap Function hoisting only applies to formal function declarations and not function expressions. Thank you 😈

@Dominus_Kelvin @DaveyHert The result is "Hola". Var lead to hoisting and the results would be undefined if the value is being accessed. But since the value of greeting is a function the value won't be undefined

Seems like @DaveyHert and I will be cooking up a lot of quizzes for you all learning JavaScript. Here is another JavaScript quiz 👇🏾 What is the output of calling greeting?

@FrontendMasters Thanks

@amolrai_dev Currently learning typescript

Dear Developers, what are you currently learning?

@codedamncom I actually thought there's only two errors in JavaScript before reading this tweet but learnt something great from this. Thanks @codedamncom .

Syntax Error: The syntax of the program is not correct. Reference Error: The JavaScript Engine cannot find a reference to a variable or function in memory. Type Error: Trying to reassign a const variable will lead to a Type Error.

Top 100 JavaScript Interview Questions and Answers in 2023: Thread [Part 3]:

Q26. What is the use of this keyword in JavaScript? In JavaScript, the this keyword points to the object currently referred. The this keyword is widely used to assign values to object attributes in constructors.

Q27. What is the difference between async and defer? In async, while parsing HTML, the browser fetches the script from the network asynchronously if we encounter a script. After fetching the script, the browser stops parsing HTML and executes the script.

After executing the script, the browser resumes the HTML parsing. In defer, while parsing HTML, the browser fetches the script from the network asynchronously if we encounter a script. The browser executes the scripts only after parsing the HTML.

Q28. What are cookies? Cookies are small data packets that the server sends to the client. The client stores the cookie inside the browser and sends it to the server on each future request.

Q29. What is the difference between let and var keywords? Both let and const are used for declaring a variable in JavaScript. The var keyword variables have function scope, while the let keyword variables have block scope.
