What it does

The proposal-optional-chaining-assignment tool allows you to assign a value to a property of an object using optional chaining, making it easier to handle nested objects and avoid null pointer exceptions.

When to use it

•When working with deeply nested objects and you need to assign a value to a property that may not exist
•When you want to simplify your code and reduce the number of null checks
•When you're using a library or framework that returns nested objects and you need to assign values to properties within those objects

Ready-to-paste prompt

const obj = { a: { b: null } }; obj.a?.b = 'value'; console.log(obj.a.b);

Heads up: Make sure your environment supports the `?.` syntax, as it is not supported in older browsers or Node.js versions, and you may need to use a transpiler like Babel to use this syntax in older environments
