how to do a for loop in javascript

var colors=["red","blue","green"];
for (let i = 0; i < colors.length; i++) { 
  console.log(colors[i]);
}

for (var i; i < 10; i++) {
  
}

let array = ['Item 1', 'Item 2', 'Item 3'];

// Here's 4 different ways
for (let index = 0; index < array.length; index++) {
  console.log(array[index]);
}

for (let index in array) {
  console.log(array[index]);
}

for (let value of array) {
  console.log(value); // Will each value in array
}

array.forEach((value, index) => {
  console.log(index); // Will log each index
  console.log(value); // Will log each value
});

for (i = 0; i < 5; i++) {
   text += "The number is " + i + "<br>";
}  

for x in range(6):
	print(x)
else:
	print("Finally finished!") 

  var i;
for (i = 0; i < cars.length; i++) { 
  text += cars[i] + "<br>";

 } 

const p = {
    "p1": "value1",
    "p2": "value2",
    "p3": "value3"
};

for (let [key, value] of Object.entries(p)) {
  console.log(`${key}: ${value}`);
}

var tops = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144];
for (let i = 0; i < tops.length; i++) {
  document.write(tops[i] + "tops");
}

var person = {fname:"John", lname:"Doe", age:25}; 
var text = "";

var x;
for (x in person) {
    text += person[x] + " ";
 } 

//text = John Doe 25

for (statement 1; statement 2; statement 3) {

      // code block to be executed

 }
