Package Exports
- ts-null-or-undefined
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ts-null-or-undefined) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
ts-null-or-undefined
Best way to check for null or undefined in typescript using a type guard. Can strip out null or undefine or complex types like T | null etc.
To use:
import Type from "ts-null-or-undefined";
let a: number | null = 0;
console.log(a*4); //Error: a might be null
if(!Type.isNullOrUndefined(a)){
console.log(a*4); //Works
}
