[Eliminate] ↘️

Eliminate is a utility that analyzes your TypeScript code to identify
variables and functions that are defined but only used once and are not
exported. It then eliminates these definitions and replaces their usage with
their initializers, optimizing your code for better readability and performance.

let a = 5;
let b = 10;
let c = a + b;
console.log(c);

console.log(5 + 10);

Feature 📦

- TypeScript support with type-checking
- Variable & Function Usage Analysis: Analyzes the code to count how many
times each variable and function is used.
- Export Detection: Ensures exported variables and functions are not
removed.
- Code Transformation: Removes unnecessary variable and function
declarations and replaces their usage with initializers.
- Complex Scenarios Handling: Handles destructuring, default parameters,
nested scopes, and type annotations.
- Configuration Options:
- Comment: Whether to preserve symbols with comments (defaults to true).
- Max: Maximum size of expressions to inline (defaults to 100 nodes).
- Async: Whether to preserve async/await expressions (defaults to
false).
- Const: Whether to preserve const variables (defaults to false).
- Function: Whether to preserve functions (defaults to false).
- Debug: Enables debug mode for verbose logging (defaults to false).
