Discussion

The convert_ts_to_js() function converts one or more TypeScript files (files that end with the .ts extension) to JavaScript syntax. The resulting files are saved with a .js extension using the same name as the filename specified for the TypeScript files.

dim tsFiles as c =<<%files%
C:\aa\example\example.WebProjects\JavaScript.WebProject\typescript\greeter.ts
C:\aa\example\example.WebProjects\JavaScript.WebProject\typescript\students.ts
%files%

dim results as c = ""

results = convert_ts_to_js(tsFiles)
? results
= "[]"

The next example demonstrates a conversion where several errors occurred:

dim tsFiles as c =<<%files%
C:\aa\example\example.WebProjects\JavaScript.WebProject\typescript\greeter_err.ts
C:\aa\example\example.WebProjects\JavaScript.WebProject\typescript\students_err.ts
%files%

dim results as c = ""

results = convert_ts_to_js(tsFiles)
? results
= [
  {
    "filename": "C:/aa/example/example.WebProjects/JavaScript.WebProject/typescript/greeter_err.ts",
    "error": "Duplicate function implementation.",
    "line": 1,
    "column": 10
  },
  {
    "filename": "C:/aa/example/example.WebProjects/JavaScript.WebProject/typescript/greeter_err.ts",
    "error": "Cannot redeclare block-scoped variable 'user'.",
    "line": 5,
    "column": 5
  },
  {
    "filename": "C:/aa/example/example.WebProjects/JavaScript.WebProject/typescript/students_err.ts",
    "error": "Duplicate function implementation.",
    "line": 13,
    "column": 10
  },
  {
    "filename": "C:/aa/example/example.WebProjects/JavaScript.WebProject/typescript/students_err.ts",
    "error": "Cannot redeclare block-scoped variable 'user'.",
    "line": 17,
    "column": 5
  }
]
