I would like to seperate the key and value from an object in typescript for that i have used the following code which returns only values but keys are not displayed.

Object.keys(data).forEach(key=> {
    console.log('keys', data[key]);     
});

But when i use the below function in javascript it gives me the key and value correctly can anyone tell me how to do the same in typescript to get the key and values from an object.

angular.forEach(data, function (value, column) {
    columns.push(column);
    values.push(value);
  });

• In your first snippet you can just add console.log(key) and it will display keys as wel – Freeman Lambda Commented Jun 19, 2017 at 13:22
• data.forEach((data)=>console.log(data.key + " " + data.value)); pure Javascript way to do it. – Hassan Imam Commented Jun 19, 2017 at 13:25

What you get with data[key] is the value:

Object.keys(data).forEach(key => {
    console.log('key', key);     
    console.log('value', data[key]);     
});

If you want to loop over an object, you can simply use for...in too:

for (var key in data) {
    if (data.hasOwnProperty(key)) {
        console.log('key', key);
        console.log('value', data[key]);
    }
}
