Remove nullish coalescing operator
The @babel/plugin-transform-nullish-coalescing-operator package allows Babel to transform nullish coalescing operator (??) syntax into equivalent JavaScript code that can run in environments that do not support this operator. The nullish coalescing operator is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand.
Transform nullish coalescing operator
This feature transforms the nullish coalescing operator (??) into equivalent JavaScript code. In this example, if 'foo' is null or undefined, 'bar' will be set to 'default value'. Otherwise, 'bar' will be set to the value of 'foo'.
const foo = null;\nconst bar = foo ?? 'default value';
This package allows Babel to transform optional chaining (?.) syntax, which is somewhat related to the nullish coalescing operator in that it helps with dealing with null or undefined values. However, optional chaining is used to access properties of an object without having to explicitly check if each reference in the chain is null or undefined.
While not a direct equivalent, @babel/preset-env includes support for transforming nullish coalescing operators among many other JavaScript features based on the target environment. It's a broader solution for compiling modern JavaScript down to a version compatible with older browsers or environments.
