How To define an array

Hi All,

I wrote the below code : 

<#assign content=get_custom_list ("9e3344c0-a641-11e0-9b98-12313d0232b0")>
${content}
<#assign array=[]>
<#list content as x>
<#assign array=array+ [x.value]>
</#list>
${array}

*the results is*
content :  [{"value":"4","label":"Jordan 1"},{"value":"13","label":"BEYROUTH
DT"},{"value":"17","label":"Jordan3"},{"value":"18","label":"Moussa
Site"},{"value":"20","label":"mousa"}]

*array* :  ["4","13","17","18","20"] 

My Question is regarding array's result, when I write this code <#assign
array=[x.value]> instead of the <#assign array=array+ [x.value]>
*the result will be * 

["20"] so why I need to define this line: *array +*, also I need a useful
link about an array(*how to define an array*)

*Regards,
Mousa Gharaibeh*
