In Javascript, you can quickly update other variables with just a one-line conditional statement

Is there a way to simplify this code into one line without using an if-else statement? For example, updating all variables when a specific condition is met?

const dogStatus = present ? "bark" : "beep";
const catStatus = present ? "meow" : "meep";
const fishStatus = present ? "blub" : "bleeboop";

Answer №1

To achieve this, you can utilize the conditional operator and destructuring in the following way:

const [dogStatus, catStatus, fishStatus] = present ? ['bark', 'meow', 'blub'] : ['beep', 'meep', 'bleeboop'];

In terms of code organization, it is worth considering using a single variable instead of multiple standalone ones whenever feasible; this approach is preferred in most scenarios:

const status = present
  ? { dog: 'bark', cat: 'meow', fish: 'blub' }
  : { dog: 'beep', cat: 'meep', fish: 'bleeboop' };
