Accessors are only available when targeting ECMAScript 5 and higher

I am trying to run this code but it is giving me following errors:

Animal.ts(10,13): error TS1056: Accessors are only available when targeting ECMAScript 5 and higher. Animal.ts(14,13): error TS1056: Accessors are only available when targeting ECMAScript 5 and higher.

interface IAnimal{
    name : string;
    sayName():string;
}

class AnimalImpm implements IAnimal{
    private _name : string = '[Animal]';
    get name():string{
        return this._name;
    }

    set name(name:string){
        this._name = name;
    }

    constructor(name:string){
        this.name = name;
    }

    sayName():string {
        console.log(`My name is ${this.name}`);
        return "Hello";
    }
}

Solution 1:

The only thing which worked for me was to specify the Target on macOS and Windows. Please note the parameter -t is standing for Target.

tsc -t es5 script.ts

You can run the command on your terminal.

Solution 2:

try setting up a tsconfig.json file in your project:

{
  "compilerOptions": {
    "target": "es5"
  }
  "files": []
}

that will tell the typescript compiler to target a version specifically.
