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);
}
}
}
};
