Serialize html form with vanilla js

Question

I have a form, I want to push the inputs when they filled into an array but making the whole data into an object first, from my structure below, when form is filled, push all the data that is filled into an object then push that object into an array, how can I solve this, been racking my head since, and nothing seems to come. the accounts array is behaving more like a container Object below, how can i pass the inputs into objects then pass them into the accounts array Javascript
