Configuring TypeScript using tsconfig.json 

tsconfig is also called the root file of a TypeScript project. It initializes your TypeScript project and uses the specific configuration rules while compiling ts. Let us have a look at some important rules and what they are meant for:

{//On saving the ts file, compile the ts to js    "compileOnSave": true,    "compilerOptions": {//Targeting option for ecmascript versions        "target": "es5",//Library files that need to be included for target        "lib": [            "es2017",            "dom"        ]    }} 

The global tsconfig file is inherited using the extend property in a specific source directory 's tsconfig.json.
