in mule 4 transformer Is it possible to use above defined key below

Question

I am working on mule 4. I want to use the key defined above in transformer below. for example, my transformer is

%dw 2.0
output application/json
---
{
    name : usama,
    age : 24,
    value: age
}

here in the third key i.e. "data" I want to use the value of "age" key.

Can anyone help?

the output should be as defined below

{
    name : usama,
    age : 24,
    value: 24
}

the top is not valid dataweave as 'usama' and 'age' aren't defined as variables or functions. If they're strings, please add quotes around them. — utechtzs, Aug 22 '19 at 12:48

Hi you can either define a global variable and reference it in both places or use a do block

%dw 2.0
output application/json
var age = 24
---
{
    name : "usama",
    age : age,
    value: age
}

Do block example: do { var age = 24 --- { name: "usama", age: age, value: age } } – jerney Aug 22 '19 at 18:22
Thanks. it is working. I just want to confirm that defining a global variable is the only way. – M.Usama Aug 23 '19 at 09:34
