Transform Array to Object

[turbopasi]

If part of the data looks like this

someArray : [
  { id : "A", value : "10" },
  { id : "B", value : "20" },
  { id : "C", value : "30" }
]

can this part be transformed to

someObject : {
  A : { id : "A", value : "10" },
  B : { id : "B", value : "20" },
  C : { id : "C", value : "30" }
}

?

Maybe if the run function in an operate block gets passed the whole item you could do something like this

operate : [
  {
    run : function (val, item) {
      item.someObject[val.id] = val;
      return val;
    },
    on : "someArray"
  }
]

Just a naive idea basically but I wondered if there is a functionality already built-in. Mapping an Array into an Object is something I use very often.

👆 I played around and turned out changing this

123
124   this.setValue(item,method.on,fn(this.getValue(item,method.on), context ));
125

to this

123
124   this.setValue(item,method.on,fn(this.getValue(item,method.on), context, item));
125

along with using nested maps already gave me the possibility to transform an array into an object using a specified key. Would this be considered a good idea ?

Sorry for the delay. Are you asking if it is a good idea in general? Or if it is a good idea to incorporate into the package for others to use?

Initially I was asking if there is already a way to transform an Array into an Object. If not - yes I believe this would be a great addition also for others. The workaround I found after that was just a quick fix for my use case.
