Strategy for Merging Arrays

[ryanfitzer]

We can either:

• dedupe based on value.
• dedupe based on value at same index.
• Array#concat

Since version 2.0.0, If the value at the specified path resolves to an array, it is concatenated with the src value. Otherwise, arrays are still overwritten.

My current thoughts on support for a behavior other than overwriting is to allow a function to be supplied as a second argument when initializing a namespace. For example:

const ns = nmsp( initialValue, ( dest, src ) => {
  return dest.reduce( ( accum, value ) => {
    // Conditionally modify the accumulator
    return accum;
  }, [])
})

Supporting all the possible variations users could possibly need would cause bloat and remove one of the main benefits of the library.
