What is @babel/helper-optimise-call-expression?

@babel/helper-optimise-call-expression is a utility package within the Babel ecosystem designed to optimize call expressions in JavaScript code. It helps in transforming and optimizing function calls to improve performance and efficiency during the code compilation process.

What are @babel/helper-optimise-call-expression's main functionalities?

Optimize Call Expressions

This feature optimizes a call expression by transforming the function call to a more efficient form. The code sample demonstrates how to use the `optimiseCallExpression` function to optimize a call to `myFunction` with arguments `1` and `2`.

const { default: optimiseCallExpression } = require('@babel/helper-optimise-call-expression');
const t = require('@babel/types');

const callee = t.identifier('myFunction');
const args = [t.numericLiteral(1), t.numericLiteral(2)];
const optimizedCall = optimiseCallExpression(callee, null, args);

console.log(optimizedCall);

babel-plugin-minify-dead-code-elimination

This plugin removes dead code from the JavaScript bundle, which can lead to performance improvements. While it focuses on eliminating unused code rather than optimizing call expressions, it shares the goal of improving the efficiency of the compiled code.
