Angular: I need help loading text file data into a string

Question

I am reading data from a text file, and the reading of data works fine, and I can even console.log the data. But I am confused on how I can transfer the data into a variable. Here is my code currently:

let mazeData; //need to get this variable to equal to the 'data' in the code below

    this.httpClient.get('assets/Maze1.txt', { responseType: 'text' })
      .subscribe(data => console.log(data));

`.subscribe(data => mazeData = data)` Now you'll probably say it doesn't work because when you log `mazeData` you get nothing in the console. And then you'll face the arduous task of wrapping your head around asynchronous execution. — Robby Cornelissen, Jun 23 '20 at 03:33

All you need to do is

this.httpClient.get('assets/Maze1.txt', { responseType: 'text' })
      .subscribe(data => mazeData = data);

I suggest you read up more on subscribe. This answer might explain things more simply to you: what is .subscribe in angular?
