Change array association with object extension

I am looking to transform the assignment below into one that utilizes object spread:

bData.steps[bStepKey].params= cData[cKey]

My attempt so far has been unsuccessful.

bData= {...bData, steps:{ ...bData.steps[bStepKey], params: cData[cKey]}}

Answer №1

While the spread operator is an option, it may not be necessary in this case. However, if you insist on using it, here is how you could implement it:

bData = { ...bData, steps: { ...bData.steps, [bstepKey]: { ...steps[bstepKey], params: cData[cKey] }}};

But truthfully, there's no real advantage to using the spread operator in this scenario - your original method is actually more efficient:

bData.steps[bStepKey].params= cData[cKey]
