error: you have both a tsconfig.json and a jsconfig.json. if you are using typescript please remove your jsconfig.json file.

Having both jsconfig.json and tsconfig.json is not necessary, the Typescript 
Documentation cites:

The presence of a tsconfig.json file in a directory indicates that the directory 
is the root of a TypeScript project. 
The tsconfig.json file specifies the root files and the compiler options 
required to compile the project.

JavaScript projects can use a jsconfig.json file instead, which acts almost 
the same but has some JavaScript-related compiler flags enabled by default.

So in typescript is better to have just the tsconfig.json file
