How to Access JavaScript Object Property That Has Hyphens in the Name?

You can access JavaScript object properties that have hyphens in the name (a.k.a. kebab case) by using the bracket property accessor notation, like so:

const obj = { 'foo-bar': 123 };

console.log(obj['foo-bar']); // 123

It's the same even if the object property name has hyphens at start or the end:

const obj = { '--foo-bar-': 123 };

console.log(obj['--foo-bar-']); // 123
