This new JavaScript operator is an absolute game changer!
JavaScript is about to make async code a whole lot cleaner with the new ?= operator. It helps avoid deep nesting and bulky try-catch blocks, making code easier to understand and maintain.
The ?= operator, known as the Safe Assignment operator, was introduced as a proposal in the ECMAScript community in 2024.
Here is how it works:
The ?= operator allows functions to return a tuple [error, result].
• If an error occurs during function execution, it returns [error, null].
• If the function runs successfully, it returns [null, result].
The ?= safe assignment operator is currently a proposal and not yet part of the official ECMAScript specification. However, you can still play around with it through polyfills, with a few limitations, like needing to use = in place of the actual ?= operator.
Developers are also encouraged to contribute to its development. 1 reply
