JavaScript’s for loop is the same as that in C and Java: it lets you provide the control information for your loop on a single line.

for (let i = 0; i < 5; i++) {

for (let value of array) {
  // do something with value

for of Must be iterable

For in

The statement iterates a specified variable over all the enumerable properties of an object. For each distinct property, JavaScript executes the specified statements. A statement looks as follows:
