The Typescript object may be null even with its initial value set

1: let a: Record<string, any> | null = {};
2: a['b'] = 2;

Encountered the

TS2531: Object is possibly 'null'
error on Row 2 despite having an initial value.

To address this issue, the code was updated as follows:

1: let a: Record<string, any> | null = {};
2: if (a) {
3:   a['b'] = 2;
4: }

The inclusion of the if condition is actually unnecessary since a has the value {}. It is only added for tslint compliance. Is there a way to eliminate this unnecessary if condition?

Answer №1

One way to utilize the Non-null assertion is by doing this:

x!['y'] = 10;
