JavaScript is a versatile, high-level programming language primarily used for web development to create interactive and dynamic content.

• Client-side scripting: JavaScript runs in the user's browser, enabling dynamic content updates without reloading the page. Example: Form validation.

• Event-driven programming: JavaScript can respond to user actions like clicks and keyboard input. Example: Dropdown menus that expand on cl...read more

JavaScript is primarily an interpreted language, but modern engines use Just-In-Time (JIT) compilation for performance.

• JavaScript code is executed by the browser's JavaScript engine, which interprets the code line by line.

• Modern JavaScript engines like V8 (Chrome) and SpiderMonkey (Firefox) use JIT compilation to improve performance.

• JIT compilation translates JavaScript code into machine code at runtime, allowing for f...read more

A variable in JavaScript is 'undefined' if it is declared but not assigned a value.

• In JavaScript, a variable declared without a value is 'undefined'. Example: let x; // x is undefined.

• If a variable is declared and assigned 'undefined', it is still considered 'undefined'. Example: let y = undefined; // y is undefined.

• Accessing a non-existent property of an object also returns 'undefined'. Example: let obj = {}; console....read more

Loops in programming allow for repeated execution of code, enabling efficient handling of repetitive tasks.

• Loops help automate repetitive tasks, reducing code redundancy.

• For example, a 'for' loop can iterate through an array: for (let i = 0; i < array.length; i++) { console.log(array[i]); }

• They can control the flow of execution based on conditions, like 'while' loops: while (condition) { // code }

• Loops can be nested...read more

A while loop is a control flow statement that repeatedly executes a block of code as long as a specified condition is true.

• Syntax: while (condition) { // code to execute }

• The loop continues until the condition evaluates to false.

• Example: let i = 0; while (i < 5) { console.log(i); i++; } // Outputs 0 to 4

• Be cautious of infinite loops; ensure...read more

An 'if' statement executes code based on a condition, while 'if-else' provides an alternative path if the condition is false.

• An 'if' statement checks a condition and executes code if true.

• Example: if (x > 10) { console.log('x is greater than 10'); }

• An 'if-else' statement provides an alternative action if the condition is false.

• Example: if (x > 10) { console.log('x is greater than 10'); } else { console.log('x is ...read more
