Bug Report
When I upgrade @babel/types to 7.8.0, the following TypeScript source files had some compilation errors:
import {
arrowFunctionExpression,
identifier,
blockStatement,
returnStatement,
program,
variableDeclaration,
variableDeclarator,
stringLiteral,
} from '@babel/types';
// error TS2554: Expected 4-7 arguments, but got 2.
arrowFunctionExpression(
[identifier('arg')],
blockStatement([returnStatement(identifier('arg'))]),
);
// error TS2554: Expected 5 arguments, but got 1.
program([
variableDeclaration('const', [
variableDeclarator(identifier('foo'), stringLiteral('bar')),
]),
]);
I followed the error message and fixed it like this:
arrowFunctionExpression(
[identifier('arg')],
blockStatement([returnStatement(identifier('arg'))]),
false,
false,
);
program(
[
variableDeclaration('const', [
variableDeclarator(identifier('foo'), stringLiteral('bar')),
]),
],
undefined,
undefined,
undefined,
'',
);
Typescript compilation was successful,But when I use node to execute the compiled JS file,@babel/types threw errors:
Error: ArrowFunctionExpression: Too many arguments passed. Received 4 but can receive no more than 3
Error: Program: Too many arguments passed. Received 5 but can receive no more than 4
