Mulesoft Joining Arrays that occur one after another in a loop

Question

I'm fairly new to mulesoft, kindly help me with this one.

I'm having a http component in a for each loop,

for the first iteration it gives a payload like:

[
{
"Value1": "xxxx",
"Value2": "yyyy",
"Value3": "zzzz"
},
{
"Value1": "qqqq",
"Value2": "eeee",
"Value3": "rrrr"
}
]

and I'm storing this payload in a variable "var1"

for the second iteration it gives a payload like:

[
{
"Value1": "1234",
"Value2": "5678",
"Value3": "0987"
},
{
"Value1": "qqqq",
"Value2": "5yy4",
"Value3": "9jf7"
}
]

I need to combine them in a way that the result should be

[
{
"Value1": "xxxx",
"Value2": "yyyy",
"Value3": "zzzz"
},
{
"Value1": "qqqq",
"Value2": "eeee",
"Value3": "rrrr"
},
{
"Value1": "1234",
"Value2": "5678",
"Value3": "0987"
},
{
"Value1": "qqqq",
"Value2": "5yy4",
"Value3": "9jf7"
}
]

and store it in a variable, so that I can call it to set payload outside the for each loop.

Thank you for the help !!

You can make use of expression transformer to concat the two Vars. If you want to do any more operations make use of Dataweave like below

flatten <listOfLists> => <mergedList>
