mapAssets: mapData ? mapData : {},

// eslint will write this

ESLint might suggest simplifying this code by using the Boolean value of stations directly:

mrtstns: Boolean(stations),

 

This code assigns the boolean value of stations to mrtstns. If stations is truthy, mrtstns is set to true. If stations is falsy, mrtstns is set to false.

 

Alternatively, ESLint might suggest a simplified version of the ternary operator, like this:

mrtstns: !!stations,

 

This code assigns the double negation !! of stations to mrtstns. If stations is truthy, !!stations evaluates to true, and mrtstns is set to true. If stations is falsy, !!stations evaluates to false, and mrtstns is set to false.
