use object.keys https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys you use Object.keys(obj) // if you need the keys of the object you use Object.values(obj) // if you need the values of the object Venzee: |

Use the Array.from() method. Pass your object within the from function. 1 Like |

The last time I check object can be looped easily or did I not understand the question Var obj = {1:"ara",2:"test"} For(var i in obj) { Var value = obj[i] } 2 Likes |

Venzee: Be concise and elaborate when when you want to ask technical questions to enable people help you better. Also, endeavor to reply to suggestions to allow people follow up with you according. If you have found a solution, say so to let others know what eventually worked out. In the example object you provided above. The following object methods would return an array as this: Object.keys(obj) = [ 'a', 'b', 'c' ]; Object.values(obj) = [ "venzee", 23, false]; Object.entries(obj) = [ [ 'a' : "venzee" ], [ 'b' : 23 ], [ 'c' : false ] ]; All the above methods should give a "Real" array, which you can loop over afterwards using something like map or forEach If you just want to loop over directly, you can do this... // Looping over all the values: for (let value of Object.values(obj)) { alert(value); // "venzee", -> 23 -> false in that order }; That should solve your problem 1 Like |

jelel6: Nawahooo for js devs here. Just dey write in nonsense. This is the only person wey dey reason normal with the question the op is asking. Also, for...in loop is used to iterate object but it's not for best practice. So the options this author gave is cool. Just read more on them op. Besides, I sell paid udemy courses for low price. |

Oga Google is your friend na. There's a high order function in JavaScript called 'map'. You can use map to loop through an object |
Re: How Do I Convert Object To Arrey In Javascript by Johnmattee(m): 8:27am On Mar 08, 2020 |
benedictuyi:You can't use map function on a plain object unless you find a way to convert it to an array and can filter through using filter function. 1 Like |
