The forEach() method

forEach()

The forEach() method is used to loop through all elements of an array and calls a function (callback function) for each element in the array. The callback function has access to the current element, index, and the entire array on every loop.

```
// Syntax
myArray.forEach(callbackFn)
myArray.forEach(function(element, index, array){ /* ... */ })
```

For example: 

```
let staff = [
    { name: "John Doe", salary: 120 },
    { name: "Jane Doe", salary: 350 },
    { name: "Karl Don", salary: 710 }
];
 let totalSalary = 0;

staff.forEach(person => {
  totalSalary += person.salary;
})

console.log(totalSalary);

staff.forEach(person => {
  let sentence = `${person.name} earns ${person.salary}`
  console.log(sentence);
})`
```
