How does esprima.parse work?

esprima.parse is a JavaScript parser that takes in source code as a string and generates a corresponding abstract syntax tree (AST) that represents the structure of the code. It follows the ECMAScript specification for parsing the code and can be used for various code analysis and manipulation tasks. The resulting AST can be traversed and modified using different libraries and tools.

const esprima = require("esprima");

const codeString = "const a = 1; let b = 2;";
const ast = esprima.parse(codeString);

console.log(ast);

In this example, esprima.parse is used to parse the codeString variable and generate an Abstract Syntax Tree (AST) for the JavaScript code. The resulting AST is then logged to the console for inspection.
