traverse an object in javascript code example
Example 1: javascript iterate over object keys and values
const object1 = {
a: 'somestring',
b: 42
};
for (let [key, value] of Object.entries(object1)) {
console.log(`${key}: ${value}`);
}
// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed

if (Object.prototype.hasOwnProperty.call(obj, prop)) {
// do stuff
}
}
