Convert array assignment through object spread

Question

I want to convert the following assignment to something that uses object spread instead:

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

I have tried below with no luck.

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

You don't need the spread operator, but if you really wanted to use it:

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

Although it's not useful at all in this situation as you don't need to spread anything - your initial approach is much better:

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

Compiler says cannot find name steps

Thank you I got it to work because of you. Didn’t know I had to put the index in a bracket.

By the way, JavaScript is interpreted not compiled.

Thanks. The reason why I’m using spread is because of this stackoverflow.com/questions/44288164/…

Typescript is compiled though :)
