Merge two objects with ES6

Question

I m sure this question has been asked before but I can t quite find the answer I m looking for  so here goes   I have two objects  as follows   const response       lat  -51 3303    lng  0 39440    let item       id   qwenhee-9763ae-lenfya     address   14-22 Elder St  London  E1 6BT  UK      I need to merge these together to form this   item       id   qwenhee-9763ae-lenfya     address   14-22 Elder St  London  E1 6BT  UK     location        lat  -51 3303      lng  0 39440         I know I could do it like this   item location      item location lat   response lat item location lng   response lng   However  I feel that this is not the best way to do it anymore  because ES6 introduced the cool destructuring assignment stuff  I tried deep object merging but it s unfortunately not supported    I also looked through some ramda functions but couldn t see anything that was applicable   So what is the best way to merge these two objects using ES6

You can use Object assign   to merge them into a new object    x000D   x000D  const response     x000D    lat  -51 3303  x000D    lng  0 39440 x000D    x000D   x000D  const item     x000D    id   qwenhee-9763ae-lenfya   x000D    address   14-22 Elder St  London  E1 6BT  UK  x000D    x000D   x000D  const newItem   Object assign     item    location  response     x000D   x000D  console log newItem    x000D   x000D   x000D    You can also use object spread  which is a Stage 4 proposal for ECMAScript       x000D   x000D  const response     x000D    lat  -51 3303  x000D    lng  0 39440 x000D    x000D   x000D  const item     x000D    id   qwenhee-9763ae-lenfya   x000D    address   14-22 Elder St  London  E1 6BT  UK  x000D    x000D   x000D  const newItem        item  location  response       or      response   if you want to clone response as well x000D   x000D  console log newItem    x000D   x000D   x000D

Another aproach is   let result        item  location        response       But Object spread isn t yet standardized   May also be helpful  https   stackoverflow com a 32926019 5341953
