Replace switch and if-else on Literal Object in JavaScript (TypeScript)

Posted on | by Oleg K.

Alternative syntax with Literal Object:

const x = 0;

const height = {
  [true]: 0,
  [x < 100]: 100,
  [100 <= x && x < 200]: 200,
  [x >= 200]: 250,
}[true];

console.log(height); // you can see "100"
