shows false positive when extension is included in import statement i.e. import calc from "./calculator.ts" instead of "./calculator"

[demonhue]

Calculator.ts

function add(num1: number,num2: number): number {
    return num1 + num2;
}
function subtract(num1: number,num2: number): number {
    return num1 - num2;
}

function multiply(num1: number,num2: number): number {
    return num1 * num2;
}

function divide(num1: number, num2: number): number {
    if (num2 !== 0) {
        return num1/num2;
    } else {
        return NaN;
        console.log("Error: Division by zero is not allowed.");
    }
}

function sqrt(num1: number): number{
    return Math.sqrt(num1);
}

export {add, subtract,multiply, divide, sqrt};

and rms.ts

import {add,divide, multiply, sqrt} from "./calculator.ts";
function square(a: number): number {
  return multiply(a, a);
}
function rootMeanSquare(arr: number[]): number {
  let sumOfSquares: number = 0;
  arr.reduce((sumOfSquares: number, value: number): number => {
    return add(sumOfSquares,square(value));
  });
  return sqrt(divide(sumOfSquares, arr.length));
}
let arr = [1, 3, 5];
console.log(rootMeanSquare(arr));

and tsconfig.json

  "compilerOptions": {
    "target": "es2016",

    "skipDefaultLibCheck": true,

  },
}

• It shows that all the exports of the file calculator.ts are unused
• but when I import like import {add,divide, multiply, sqrt} from "./calculator"; it works as intended.

hm it's a bug indeed, then.

[demonhue]

similar issue with ".tsx" extension

[demonhue]

@mrseanryan It would really help if this bug gets resolved quickly. I know you guys must be busy so I can't really demand things.But I think this shouldn't take long to fix.

[mrseanryan]

Fixed thank you! Releasing in 10.0.0
