Accessors are only available when targeting ECMAScript 5 and higher

Question

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 ECMAS

Answer 1

If you're dealing with single file you could do this

tsc your-file.ts --target ES2016 --watch

If you wants inside your tsconfig.json for entire project configuration

{ "compilerOptions": { "target": "ES2016" } "files": [] }

You may want to use either ECMAScript numeric "es6", "es7", "es8" or year of release like "ES2015", "ES2016", "ES2017".

ESNext targets latest supported ES proposed features.
