How to cloning two object in one ? I tried Object.assign() but doesn't worked.
I have this : this.props.firstLetter[i] the return of that on my console is : 
This two objects I would like to create one big object of these two.
With Object.assign(), I tried this : Object.assign(this.props.firstLetter[i]), but the result of them is only one entry, the last only. 
You have solution ?
Please.
EDIT 17/12/2017 :
