Example 1: js loop through object
const obj = { a: 1, b: 2 };
Object.keys(obj).forEach(key => {
console.log("key: ", key);
console.log("Value: ", obj[key]);
} );
Example 2: js object keys
var myObj = {no:'u',my:'sql'}
var keys = Object.keys(myObj);//returnes the array ['no','my'];
Example 3: javascript access property values list of objects
// Access all properties and values in a JS object:
let valuesArray = Object.entries(MyObject);
for (let value of valuesArray) {
document.write(value + "<br>"); // value is the property,value pair
}
/* Result: propName,value
propName,value
...
For clarity: */
let person = {
name: "Piet",
age: 42
};
Object.keys(person) // = ["name", "age"]
Object.values(person) // = ["Piet", 42]
Object.entries(person) // = [ ["name","Piet"], ["age",42] ]
