如何在数组中的每个单词之间打印空格

Question

I remember seeing a function on w3school where you can print out all the words of an array and add a space between them, But no matter how much I google I can't find it.

Example of how it could look:

function printWords() {
  var array = ["Car", "Bus", "Motorcykle"];
  print(array.addSpaces());
}

Thanx in advance

Answer 1

Use Array.prototype.join() . You can specify a character to put between the values, in your case:

array.join(' ');

Answer 2

ASDFGerte has exactly the answer:

function printWords() {
  var array = ["Car", "Bus", "Motorcykle"];
  print(array.join(" "));
}

Answer 3

You can store the contents of the array with the spaces in between, in the new variable array_content as described below, by consecutively iterating and storing each item of the array with the space in between.

 function printWords() { var array = ["Car ", "Bus ", "Motorcykle "]; var res = ' '; var array_content = ''; for (i = 0; i < array.length; i++) array_content = array_content + array[i] + res; console.log(array_content); } printWords();
