Fundamentals / Code Structure

Statements

Statements are syntax constructs and commands that perform actions. 
 
/**
 * Semicolon can be omitted, but not recommended
 * A semicolon is not assume before square brackets
 */

console.log("Hello");   // Hello
console.log("World");   // World
console.log(1 +         // 6
    2 + 3
);

try {
    console.log("abc")  // Look Here
    [1, 2].forEach(console.log); 
} catch (err) {
    console.log(err.name); // TypeError
}

Comments

In most editors, you can comment out by pressing the Ctrl + / 
 
/**
 * One-line comments start with two forward slash characters //
 * Multiline comments start with a forward slash and an asterisk /*
*/
 
console.log('Hello'); // one line comment
