entries (obj). forEach (([key, value]) => console. log (` ${key}: ${value} `)); // "foo: bar", "baz: 42" Specifications Specification The Object.keys () function returns an array of the object's own enumerable properties. You can then iterate over each key in the object using forEach (). const obj = { name: 'Jean-Luc Picard', rank: 'Captain' }; // Prints "name Jean-Luc Picard" followed by "rank Captain" Object.keys (obj).forEach (key => { console.log (key, obj [key]); }); get(key) – returns the value associated with the key. If the key does not exist, it returns undefined. has(key) – returns true if a value associated with the key exists, otherwise, return false.
