Es un programa para parsear un fragmento de código.

const should = require('chai').should(),
    espree = require('../src/logging-espree.js');


const test1 = `function foo(a, b) {
    console.log(\`Entering foo(\${ a },\${ b }) at line 1\`);

}(2));`;

const test3 = `(e => {
    console.log(\`Entering <anonymous function>(\${ e }) at line 1\`);
    return e + 1;
})(4);`;

//console.log(espree.addLogging(test1));
