As one of several questions on a javascript screen, how reasonable is it to show the following and expect answer in 30 seconds or so with no code tools, just reading and understanding the code as written? Too much, too little, irrelevant; feedback welcome. What value is written to the console from the following? const array = [1, 3, 6, 8]; const result = array  .map(x => x * 2)  .filter(x => x > 10)  .reduce((a, v) => a + v, 0); console.log(result);

Ram Ram Sara ne! Today, I learned about "Browser Object Model" BOM - Browser Object Model - represents browser's functionalities - set of features Some features are 1. Window Object 2. Navigator Object 3. Screen/History/URL Bar Runtime Environment for JavaScript - software which provide environment to execute JavaScript Code - Browser - NodeJS - DinoJS - BunJS Window - It is an Object - collection of features, functions - window.alert("Hey); --> run on console - window.location - window.location.reload(); -> reload the page - window.screen -> to know about height and width of the screen - window.location.assign("url"); -> to redirect to a specific url - navigator.geolocation.getCurrentPosition(); -> gets current lattitude and longitude coordinates Like this, we have objects to access mic and camera also.

A **closure** in JavaScript is when an inner function has access to the outer function’s variables, even after the outer function has finished running. This allows the inner function to "remember" and use those variables later. ### Simple Example: ```javascript function outer() { let count = 0; return function inner() { count++; console.log(count); }; } const counter = outer(); counter(); // 1 counter(); // 2 ``` Here, `inner` is a closure because it keeps access to `count` from the `outer` function, even after `outer` is done executing. **Closures** are useful for creating private variables and maintaining state in your functions.

JAVASCRIPT FUNCTION THAT CAPITALIZE THE FIRST LETTER OF A STRING function capitalizeFirstLetter(str) {  return str.charAt(0).toUpperCase() + str.slice(1).toLowerCase(); } const name = "john Doe"; const newName = capitalizeFirstLetter(name); console.log(newName); // Output: John Doe

solve this javascript question:- comment your answer const user={     age:"23" }; function confusion(){     if(user.age=="23"){         return user.age ="adult";     }     if(user.age=="adult"){         return user.age ="23";     } } console.log(user.age);
