Typescript 3.7 introduced 2 amazing operators: Optional chaining and Nullish coalescing here's how to take advantage of them

	// Before
	const val = otherVal !== null && otherVal !== undefined && otherVal.prop !== null && otherVal.prop !== undefined && otherVal.prop.name;

	// With optional chaining
	const val = otherVal?.prop?.name;
	const name = company.employees?.[0]?.name;

	// let's say you want to return a undefined value, that's when nullish coalescring operator comes in handy.
	const val = otherVal?.prop?.name ?? 'Anonymous';
	const name = company.employees?.[0]?.name: 'User';
