Creating one more field in list of objects by using the fields in same objects

[GBekkanti]

Hi Team,
I have the below input data :
[
{
ID:123
“Name”:“Tony”,
“Age”:24
},
{
ID:124
“Name”:“Sam”,
“Age”:36
},
{
ID:125
“Name”:“Glenn”,
“Age”:58
}]

I need to add one more field ‘halfAge’ to the above and output data should be like below:

[
{
ID:123
“Name”:“Tony”,
“Age”:24,
“halfAge”:12
},
{
ID:124
“Name”:“Sam”,
“Age”:36
“halfAge”:18
},
{
ID:125
“Name”:“Glenn”,
“Age”:58,
“halfAge”:29
}]

Can you please let me know the Expression language for this?

Thanks in Advance!

One of the functions available in the expression language is zip, which enables you to merge two arrays. Does this help?

GBekkanti:

‘genderArray’:[‘Male’,‘Female’,‘Male’]

@GBekkanti

sounds like you want to do something like this which you can do using sl.zip()

sl.zip($items, $genderArray).map(pair => pair[0].extend({ Gender: pair[1] }))

Thanks @cjhoward18, @cstewart

It works fine. Thank you
