When you need to iterate through an object’s properties in JavaScript, you have several options available. One way is to use a 'for' in loop, which allows you to loop through each property of the object one by one. Another approach is to use the methods ‘Object.keys()’, ‘Object.values()’, or, ‘Object.entries()’ introduced in ES6. These methods provide arrays of the object’s keys, values, or key-value pairs, respectively, which you can then iterate through using traditional array looping techniques like for or forEach. These techniques offer different ways to access and work with an object’s properties, providing flexibility and convenience when handling complex data structures in JavaScript.
