Task 5: Determine the result of the code What will be the result of executing the following code? Why?|

let foo = { n: 1 };
let bar = foo;
bar.n = 2;

console.log(foo.n);

let a = [1, 2, 3];
let b = a;
b.push(4);

console.log(a);

let x = "hello";
let y = x;
y = "world";

console.log(x);

✅ Сhoose the correct option 📝 🔎 Look for a hint: 1. 2 (bar and foo point to the same object) 2. [1, 2, 3, 4] (a and b point to the same array) 3. "hello" (strings are primitives, passed by value) Explanation: Objects and arrays are passed by reference, so bar.n changes foo.n, and b.push(4) changes a. Primitive types (string, number, boolean) are passed by value, so changing y does not affect x.

Task 4: Using let, const, var What will be the result of running the code? Why?

console.log(a);  
var a = 10;

console.log(b);  
let b = 20;

if (true) {
    var x = 50;
}
console.log(x);

if (true) {
    let y = 60;
}
console.log(y);

✅ Сhoose the correct option 📝 🔎 Look for a hint: 1. undefined (due to hoisting, variable is declared but not yet initialized) 2. Error! Variable is declared but is in the "dead zone" (TDZ) 3. 50 (var variable is accessible outside the block) 4. Error! y is only defined in the if block Explanation: var is hoisted but not initialized, so console.log(a); prints undefined. let and const are not hoisted, so console.log(b); throws an error. var is not block scoped, so x is accessible outside the block. let is scoped to {} and y is not accessible outside the if block.

Task 3: Type casting What will be printed to the console? Explain why.

console.log("5" + 3);  
console.log("5" - 3);  
console.log(5 + true);  
console.log("10" * "2");  
console.log("10px" - 2);  
console.log(null + 5);  
console.log(undefined + 5);  
console.log(!!"false");  
console.log(!!0);  
console.log(Boolean([]));

✅ Write your version in the comments 📝 🔎 Look for a hint: 1. "53" (concatenation, since "5" is a string) 2. "2" (the string "5" is converted to a number) 3. "6" (true is converted to 1) 4. "20" (both values are converted to numbers) 5. "NaN" (you can't subtract a number from a string of letters) 6. "5" (null is converted to 0) 7. "NaN" (undefined can't be a number) 8. "true" (a non-empty string is truthy) 9. "false" (0 is falsy) 10. "true" (an array is a truthy value) Explanation: JS automatically converts strings and numbers in arithmetic operations. null becomes 0, undefined becomes NaN. !! is a double logical negation that turns a value into true or false.

Task 2: Determine the data type What will be logged to the console in each case? Explain why.

console.log(typeof "hello");  
console.log(typeof 42);  
console.log(typeof true);  
console.log(typeof null);  
console.log(typeof undefined);  
console.log(typeof {});  
console.log(typeof []);  
console.log(typeof function() {});  
console.log(typeof NaN);  
console.log(typeof 100n);

✅ Write your version in the comments 📝 🔎 Look for a hint: console.log(typeof "hello"); // "string" console.log(typeof 42); // "number" console.log(typeof true); // "boolean" console.log(typeof null); // "object" (историческая ошибка в JS) console.log(typeof undefined); // "undefined" console.log(typeof {}); // "object" console.log(typeof []); // "object" (массивы тоже объекты) console.log(typeof function() {}); // "function" (фактически объект, но JS так определяет функции) console.log(typeof NaN); // "number" (NaN – специальное значение типа number) console.log(typeof 100n); // "bigint" Explanation: "typeof null" returns "object" due to a bug that has existed since early versions of JavaScript. "typeof NaN" is "number" because NaN is an invalid numeric value. "typeof []" is "object" because arrays in JavaScript are a type of object. "typeof function() {}" is "function", but in reality, it is a subtype of an object.

Task 1: Correct the mistakes The code below contains errors related to declaring and changing variables. Find and fix them.

var age = 25;
let age = 30; 

const pi;
pi = 3.14;

let name;
console.log(typeof name === "null");

✅ Write your version in the comments 📝 🔎 Look for a hint: let age = 30; // Error: Re-advertisement Use let instead of var. Now you can change the value without re-declaring the variable. age = 30; const pi; // Error Сonst variable must be initialized. We need to declare and immediately initialize const: const pi = 3.14; console.log(typeof name === "null"); // Error It is incorrect because typeof null returns "object" due to a bug in JS. You just need name === null. #jsTasks

🚸 Inline conditionals in CSS? Last week, we had a CSS WG face-to-face meeting in A Coruña, Spain. There is one resolution from that meeting that I’m particularly excited about: the consensus to add an inline if() to CSS. While I was not the first to propose an inline conditional syntax, I did try and scope down the various nonterminating discussions into an MVP that can actually be implemented quickly, discussed ideas with implemenators, and eventually published a concrete proposal and pushed for group resolution. Quite poetically, the relevant discussion occurred on my birthday, so in a way, I got if() as the most unique birthday present ever. 😀
