There are multiple ways to this one standard way is using Object.keys:

You can do

• Object.keys


• Array.Prototype.forEach

Object.keys(obj).forEach(function(key) {

   console.log(key +   + obj[key]);

});

If you are using jQuery you can use $.each() method like this:

$.each({ name: John, lang: JS }, function( k, v ) {

  console.log( Key:  + k + , Value:  + v );

});

Or you can use a for...in loop, but most people I know don't use them nowadays due to better alternatives.

for (var prop in obj) {

  console.log(obj. + prop +  =  + obj[prop]);

}

If you ever end up wanting to complicate things you can use es6 generators like this to get syntax more akin to python:

// The asterisk after `function` means that

// `objectEntries` is a generator

function* objectEntries(obj) {

    let propKeys = Reflect.ownKeys(obj);



    for (let propKey of propKeys) {

        // `yield` returns a value and then pauses

        // the generator. Later, execution continues

        // where it was previously paused.

        yield [propKey, obj[propKey]];

    }

}



let jane = { first: 'Jane', last: 'Doe' };

for (let [key,value] of objectEntries(jane)) {

    console.log(`${key}: ${value}`);

}

// Output:

// first: Jane

// last: Doe
