js parcourir array code example

Example 1: 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

Example 2: javascript foreach syntax

const marks = [12, 17, 14];
let sum = 0;

marks.forEach(mark => {
  sum += mark;
});
