how to use the defaultto function from the lodash library in typescript

To use the defaultTo function from the lodash library in TypeScript, you need to follow these steps:

1. Install the lodash library using your package manager:

npm install lodash
19 chars
2 lines

2. Import the defaultTo function from the lodash library:

index.ts
import { defaultTo } from 'lodash';
36 chars
2 lines

3. Call the defaultTo function with the value you want to check and the default value you want to use if the value is null, undefined, or NaN:

index.ts
const myValue: number | undefined = undefined;
const defaultValue: number = 0;

const result = defaultTo(myValue, defaultValue);

console.log(result); // Output: 0
164 chars
7 lines

In this example, myValue is undefined, so the defaultTo function returns the defaultValue of 0.

Note that the defaultTo function is useful for cases when you want to avoid errors caused by null or undefined values.
