Eliminate ↘️

Eliminate is a utility that analyzes your TypeScript code to identify variables that are defined but only used once and are not exported. It then eliminates these variable 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);

Features 📦

• TypeScript support with type-checking
• Variable Usage Analysis: Analyzes the code to count how many times each variable is used.
• Export Detection: Ensures exported variables are not removed.
• Code Transformation: Removes unnecessary variable declarations and replaces their usage with initializers.
• Complex Scenarios Handling: Handles destructuring, default parameters, nested scopes, and type annotations.
