for: Repeats a block of code a fixed number of times.for (let i = 0; i < 5; i++) { console.log(i); }for...in: Iterates over the properties of an object (including inherited ones if not filtered).const obj = { a: 1, b: 2 }; for (const key in obj) { console.log(key + ': ' + obj[key]); }for...of: Iterates over iterable objects (arrays, strings, Map, Set, etc.).const arr = [1, 2, 3]; for (const element of arr) { console.log(element); }while: Repeats a block of code while the condition is true.let i = 0; while (i < 5) { console.log(i); i++; }do...while: Executes the block of code once, then repeats it while the condition is true. The condition is checked at the end.let i = 0; do { console.log(i); i++; } while (i < 5);forEach(method of arrays and other iterable objects): Executes a provided function once for each element.const arr = [1, 2, 3]; arr.forEach(function(element) { console.log(element); });
