How to print elements from an array with JavaScript

Use forEach for this like below

var a = ["a", "b", "c"];
a.forEach(function(entry) {
  console.log(entry);
});

You can use a simple for loop:

for (i = 0; i < array.length; i++)
  document.writeln((i+1) + ": " + array[i]);

And use the document.writeln to print it out. See the below working snippet.

Snippet

array = ["example1", "example2", "example3"];
for (i = 0; i < array.length; i++)
  document.writeln((i+1) + ": " + array[i]);

Note: The document.writeln() is implemented differently many times. So you should use:

document.getElementById("id_of_div").innerHTML += (i+1) + ": " + array[i];

Instead of printing in a loop, I'd propose a simple functional transformation to generate a string that you can print (or use in another way):

var example = ["example1", "example2", "example3"]
var O = example.map( (e, i) => (i + 1 + "." + e) ).join(' ');
console.log(O);

It works by applying a .map() on your array, with an arrow function to combine each array element e and its index i into a string. You then just need to .join() the elements of the resulting array, using any separator you want (e.g. ' ').

Use forEach for this like below(ES6)

var a = ["a", "b", "c"];
a.forEach((element) => {
        console.log(element)
    }
);

You can use standard array methods to get the result you're after. MDN has some great documentation on array iteration methods.

var examples = ["example1", "example2", "example3"];

// You can use reduce to transform the array into result,
// appending the result of each element to the accumulated result.
var text = examples.reduce(function (result, item, index) {
    var item_number = index + 1;

    return result + " " + item_number + ". " + item;
}, "");

// You can use a variable with forEach to build up the
// result - similar to a for loop
var text = "";

examples.forEach(function (item, index) {
    var item_number = index + 1;

    text = text + " " + item_number + ". " + item;
});

// You can map each element to a new element which 
// contains the text you'd like, then join them
var text = examples.map(function (item, index) {
    var item_number = index + 1;
    return item_number + ". " + item;
}).join(" ");

// You can put them into an HTML element using document.getElementById
document.getElementById("example-text-result").innerHTML = text;

// or print them to the console (for node, or in your browser) 
// with console.log
console.log(text);

Try to use a for loop:

for (var i=0; i<array.length; i++)
    console.log(i + ". " + array[i]);

You can try this:-

var arr = ['example1', 'example2', 'example3']
for (var i = 0; i < arr.length; i++){
    console.log((i + 1) + '. ' + arr[i])
}

You can do the following to print it out in one line:

let exampleArray = ["example1", "example2", "example3"];
let result = [];

 for (let i = 0; i < exampleArray.length; i++) {    
   result += i + 1 + ". " + exampleArray[i] + " ";
 }
 console.log(result);

Just my two cents:

let array = [
  [
    ['a', 'b', ['c', 13, ['d', 22, [44, [34]]]]],
    [1, 2, 3]
  ],
  [],
  [
    ['d', 'e', 'f', 'g', 'h'],
    [4, 5, 6, 7]
  ]
];

console.log(printArray(array));

function printArray(inputArr) {
  return "[" + _printArray(inputArr).intermediateVal + "]";
}

function _printArray(inputArr) {
  if (Array.isArray(inputArr)) {
    let str = "";
    for (let a = 0; a < inputArr.length; a++) {
      let result = _printArray(inputArr[a]);
      if (result.isComplexType) {
        str += "[" + result.intermediateVal + "]";
      } else {
        str += result.intermediateVal;
      }
      if (a + 1 < inputArr.length) {
        str += ", ";
      }
    }

    return {
      "isComplexType": true,
      "intermediateVal": str
    }
  } else {
    return {
      "isComplexType": false,
      "intermediateVal": inputArr
    }
  }
}

and prints this:

[[[a, b, [c, 13, [d, 22, [44, [34]]]]], [1, 2, 3]], [], [[d, e, f, g, h], [4, 5, 6, 7]]]

I was solving such a problem and I did this

const multiLanguages = ["C is fun", "Python is cool",  "JavaScript is amazing"];
for (let i = 0; i < multiLanguages.length; i++) {
  console.log(multiLanguages[i]);
}

If you want to do this in ES6 reduce will be good choice you over map. It declares predefined variable for you and event you don't need to join()

var array = ["example1", "example2", "example3"];
var op= array.reduce((ac,cur,ind)=> ac +` ${ind+1}.` + cur,'');
console.log(op);

With Map() and Join()

var array = ["example1", "example2", "example3"];
var op= array.map((e, i) =>`${i+1}.${e}`).join(' ');
console.log(op);
