Insert a new dynamic record in JSON under array field

Hi Viktor,
I want to insert new record in the below given array .If suppose there are 4 records under the value array. I want to add the 5th record in the array of value if the another input is  { "src_code" : "Active"}

“value”:
[
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“None**”,“urls”:null,“valueName”:“None”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Country**”,“urls”:null,“valueName”:“Country”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Employee”**,“urls”:null,“valueName”:“Employee”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,**“label”:“Both”,**“urls”:null,“valueName”:“Both”
}
]
{
"src_code":"Active",
"tgt_code":null
}

expected Output 
“value”:
[
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“None**”,“urls”:null,“valueName”:“None”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Country**”,“urls”:null,“valueName”:“Country”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Employee”**,“urls”:null,“valueName”:“Employee”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,**“label”:“Both”,**“urls”:null,“valueName”:“Both”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,**“label”:“Active”,**“urls”:null,“valueName”:“Active”
}
]


Please let me know if it is unclear.

Yes Viktor. and that object needs to be removed in the output. and the number of input object would be dynamic.
{
“src_code”: “Active”,
“tgt_code”: null
}
