What is @babel/helper-builder-binary-assignment-operator-visitor?

@babel/helper-builder-binary-assignment-operator-visitor is a Babel helper module that assists in transforming binary assignment operators (like +=, -=, etc.) in JavaScript code. It provides utilities to create visitors for these operators, making it easier to handle and transform them during the Babel plugin development process.

What are @babel/helper-builder-binary-assignment-operator-visitor's main functionalities?

Transforming Binary Assignment Operators

This feature allows you to transform binary assignment operators like += into their expanded form. The code sample demonstrates how to create a visitor that transforms the += operator into a binary expression using the @babel/helper-builder-binary-assignment-operator-visitor package.

const { types: t } = require('@babel/core');
const build = require('@babel/helper-builder-binary-assignment-operator-visitor');

const visitor = build({
  operator: "+=",
  build: (left, right) => t.binaryExpression(
    "+",
    left,
    right
  )
});

const plugin = {
  visitor: {
    AssignmentExpression(path) {
      if (path.node.operator === "+=") {
        visitor(path);
      }
    }
  }
};
