Deconstruct and rename values to string keys

Any way I can do something like this? I need specific names for values...

const {
  firstNm: 'my-funny-first-name',
  lastNm: 'bar-foo_Bar'
} = response;

You need to change my-funny-first-name to myFunnyFirstName, because you cannot have dashes in a variable name.

var response = {
  "firstNm" : "Billy-Bob",
  "lastNm"  : "Foo Bar"
};

const {
  firstNm: myFunnyFirstName,
  lastNm: barFooBar
} = response;

console.log(`myFunnyFirstName = ${myFunnyFirstName}\nbarFooBar = ${barFooBar}`);
.as-console-wrapper { top: 0; max-height: 100% !important; }

Variable names can't contain hyphens (-), so you can't.

But, you can still rename the destructured properties, as long as their names are valid identifiers:

const {
  firstNm: my_funny_first_name,
  lastNm: bar_foo_Bar
} = response;

Note that you can't quote those names, but you don't have to at all:

  • Valid identifier names can be written without quotes, and
  • Invalid identifier names are unallowed at that place.

You can do this, however you need to use valid variable names and you can omit the quotes. In other words:

const { firstNm: myFunnyFirstName, lastNm: barFooBar } = response

^ This will create new variables myFunnyFirstName and barFooBar to represent response.firstNm and response.lastNm, respectively.
