castArray

TS JS Deno

Casts the provided value as an array if it's not one.

Use Array.prototype.isArray() to determine if val is an array and return it as-is or encapsulated in an array accordingly.

typescript
export const castArray = (val: any): any[] =>
  Array.isArray(val) ? val : [val];
typescript
castArray("foo"); // ['foo']
castArray([1]); // [1]
