TS6133

'c' is declared but its value is never read.

Broken Code ❌

function sum(a: number, b: number, c: number) {
  return a + b;
}

Fixed Code ✔️

The best way to fix it is prefixing the unused parameter with an underscore (_) as shown below or completely removing it:

function sum(a: number, b: number, _c: number) {
  return a + b;
}

'volume' is declared but its value is never read.

Broken Code ❌

const closes = ohlc.map(([time, open, high, low, close, volume]) => close);

{
  "compilerOptions": {
    "noUnusedParameters": true
  }
}

Fixed Code ✔️

A workaround is to loosen the compiler config (not recommended, though):

{
  "compilerOptions": {
    "noUnusedParameters": false
  }
}

'b' is declared but its value is never read.

Broken Code ❌

let b;

{
  "compilerOptions": {
    "noUnusedLocals": true
  }
}

Fixed Code ✔️

You can remove the unused variable from your code or disable the check for unused variables in your TypeScript compiler config:

{
  "compilerOptions": {
    "noUnusedLocals": false
  }
}
