Creating an associative array in JS?

Question

JavaScript

How to create an associative array in JS inline? I honestly searched and couldn't find it.
An example of what I want in neutral PHP:

$arrArray = array(&quot;key1&quot; =&gt; &quot;value1&quot;, &quot;key2&quot; =&gt; &quot;value2&quot;)<br/>

Interested in a short path and in one operation

Answer 1

var arr = { key1: 'value1', key2: 'value2' };

Answer 2

<script type="text/javascript">
var arrArray1 = <?php echo json_encode($arrArray);?>;
var arrArray2 = {
  key1: 'value1'
  ,key2: 'value2'
};
var arrArray3 = [];
arrArray3['key1'] = 'value1';
arrArray3['key2'] = 'value2';
</script>

Answer 3

There are no pure associative arrays in JS.
There are objects that store key-value pairs, but there are no length, pop, shift, etc. properties.
And there are arrays that do not have keys, but have all the charms of real arrays.

For anyone else , check this out , and then it 's better to read the mana on MDN .

Answer 5

I propose here such a crutch
//key=>value; key=>value;
function array_assoc(data){
var _arr = [];
var a = data split(";");
for(var c = 0; c < a.length; c++){
var b = a[c].split("=>");
_arr[b[0]] = b[1];
}
return_arr;
}
var my_array = array_assoc("name=>Vasya;age=16;gender=male");
