Using the most recent version of ES that comes after ES2015 in Visual Studio Code

Using the most recent version of ES that comes after ES2015 in Visual Studio Code

Hey there! I'm brand new to Visual Studio and just created a simple TypeScript file called Test.ts. Check out the code below:

let hm:Map<number,String> = new Map<number,String>();
let uname=1;
let pass="String";
hm.set(uname,pass);
console.log(hm);

I tried compiling the file using tsc Test.ts

However, I encountered the following error. Can anyone help me resolve this issue? Please note that I am not working with Angular, just a regular TypeScript file.

Test.ts:1:8 - error TS2583: Cannot find name 'Map'. Do you need to change your target library? Try changing the `lib` compiler option to 'es2015' or later.

1 let hm:Map<number,String> = new Map<number,String>();

Any suggestions on how to resolve this error? Would using a tsconfig.json file be necessary, or can I directly change the editor to use a later version of es2015?

To configure the target library in your tsconfig.json file, you can specify it like this:

{
  "compilerOptions": {
    "target": "es5"
  }
}

When you run tsc with a specific filename, it does not consider tsconfig.json. To fix this, try running tsc without any additional command line arguments.

Here's what I did:

Initialized the tsconfig.json file using tsc --init;
Uncommented the "lib": [] property;
Inserted "es2015" into the lib array:
```
"lib": ["es2015"]
```
;
Typed tsc in the terminal;
Fixed bugs;
Repeated step 4;

After these actions, I successfully generated the file.js script which could be executed by using node file.js!
