Truncate every string in an array with JOLT Transformation - json

Question

I try to truncate strings in an array with JOLT. The character "^" should be removed from any string that contains it in the first position.
Sample Input:
{
"scores": [
"^aaaa",
"^bbbb",
"cccc",
"^dddd",
"eeee"
]
}
Expected Output:
{
"scores" : [ "aaaa", "bbbb", "cccc", "dddd", "eeee" ]
}
My Spec:
[
{
"operation": "modify-overwrite-beta",
"spec": {
"splittedScores": "=split('\\^',#(1,scores))",
"scores": "=join('',#(1,splittedScores))" // <--- Not working
}
}
]

Answer 1

Seems you'd need one extra shift transformation sandwiched between modify transformations to tame the subarrays such as
[
{
"operation": "modify-overwrite-beta",
"spec": {
"*": "=split('\\^',#(1,&))"
}
},
{
"operation": "shift",
"spec": {
"*": {
"*": "&"
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"*": "=join('',#(1,&))"
}
},
{
"operation": "shift",
"spec": {
"*": {
"#": "scores"
}
}
}
]
the demo on the site http://jolt-demo.appspot.com/ is
or only one shift transformation will be sufficient to use(a straightforward option) such as
[
{
"operation": "shift",
"spec": {
"*": {
"*": {
"^*": {
"$(0,1)": "&3"
},
"*": {
"$": "&3"
}
}
}
}
}
]
splitting by "$(0,1)" wildcard for the object under "^*" node. &3 represents going three levels up to grab the name of the key scores .
the demo on the site http://jolt-demo.appspot.com/ is
If ^ is being removed in the first position really matters, then the second method; if all ^ characters from any strings should be removed, then the first method should be used.
