"composable-dot-box" npm module

Objective:

The "composable-dot-box" object allows you to wrap your data in composable and immutable getters and setters.

Composability is a system design principle that deals with the inter-relationships of components. It allows the users to select and assemble data in nested structures. Immutability will make sure the setter will only return copies of your source data without changing them.

        weight: data.weight
      }))
      .map(data => {
        const name = data.name;
        const isFatorNot = Number(data.weight)>160? 'fat' : 'skinny';
