Node.js 20 LTS compatibility

LingToTypescript does not work with node.js 20 LTS.

Uncaught SyntaxError: Illegal continue statement: 'outerLoop' does not denote an iteration statement (at linq-to-typescript.js?v=09a07e09:3073:26)

So, I've updated the tests to use Node 20.10.0 and they all ran without an issue.

How are you getting this error?

After more testing, the problem is with SSR enabled. It's easy to reproduce:

Create a new project Angular 17 with SSR enabled.

In the app.component.ts:

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet } from '@angular/router';
import { from } from 'linq-to-typescript';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule, RouterOutlet],
  templateUrl: './app.component.html',
  styleUrl: './app.component.scss'
})
export class AppComponent {
  title = 'test';
  test = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

  constructor() {
    const result = from(this.test).any(x => x === `'a');`
    console.log(result);
  }
}

And the error when you build:

ng build

An unhandled exception occurred: Illegal continue statement: 't' does not denote an iteration statement
See "C:\Users\xxxx\AppData\Local\Temp\ng-ao6Efq\angular-errors.log" for further details.

No problem with an Angular 17 app without SSR enabled.

Might be related to #29

I wonder if Server-Side Rendering is trying to transpile down the async for loops with a continue outerLoop label and failing

No fix for this problem?

@ebiton-eig There is no such thing as linq-to-typescript.js; this seems to be an issue with Angular transpilation and/or minification. :/
