示例1: BinaryExpression

        const node = path.node;
        if (t.isIdentifier(node) && node.name === "n") {
            node.name = "x";
        }
    }
});

// Examples from https://github.com/thejameskyle/babel-handbook/blob/master/translations/en/plugin-handbook.md#writing-your-first-babel-plugin

const v1: Visitor = {
    BinaryExpression(path) {
        if (t.isIdentifier(path.node.left)) {
            // ...
        }
        path.replaceWith(
            t.binaryExpression("**", path.node.left, t.numericLiteral(2))
        );
        path.parentPath.replaceWith(
            t.expressionStatement(t.stringLiteral("Anyway the wind blows, doesn't really matter to me, to me."))
        );
        path.parentPath.remove();
    },

    Identifier(path) {
        if (path.isReferencedIdentifier()) {
            // ...
        }
        if (t.isQualifiedTypeIdentifier(path.node, path.parent)) {
            // ...
        }
    },
