js loop through array

var data = [1, 2, 3, 4, 5, 6];

//traditional for loop
for(let i=0; i<=data.length; i++) {
  console.log(data[i])  // 1 2 3 4 5 6
}

//using for/of
for(let i of data) {
	console.log(i) // 1 2 3 4 5 6
}

//using forEach
data.forEach((i) => {
  console.log(i) // 1 2 3 4 5 6
})
//BUT ->  forEach method is about 95% slower than the traditional for loop

//using map
data.map((i) => {
  console.log(i) // 1 2 3 4 5 6
})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 log each value
}

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

array.forEach((value, index) => {
  console.log(index); // Will log each index
  console.log(value); // Will log each value
});var txt = "";
var numbers = [45, 4, 9, 16, 25];

numbers.forEach(function(value, index, array) {
  txt = txt + value + "<br>";
});
var colors = ["red","blue","green"];
for (var i = 0; i < colors.length; i++) {
    console.log(colors[i]);
}// ES6 for-of statement
for (const color of colors){
    console.log(color);
}

// Array.prototype.forEach
const array = ["one", "two", "three"]
array.forEach(function (item, index) {
  console.log(item, index);
});

// Sequential for loop
for (var i = 0; i < arrayLength; i++) {
    console.log(myStringArray[i]);
    //Do something
}
