foreach is not a native looping structure in JavaScript. The correct looping structures in JavaScript are for, while, do...while, and for...of/for...in. JavaScript does have a forEach() method that can be used with arrays (e.g., array.forEach(callback)), but it's not a standalone loop structure—it's an array method. This is different from some other programming languages like PHP or C# that do have a foreach keyword as part of their syntax.
