Answers for "callback foreach javascript"

foreach object js

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

foreach javascript

var items = ["item1", "item2", "item3"]
var copie = [];

items.forEach(function(item){
  copie.push(item);
});
