esprima 与 escodegen 格式化代码（带注释）

var jsContentStr1 = fs.readFileSync(path.join(__dirname,"output","newGenEpos.js"),"utf-8");

let jsBodyArr1 = esprima.parseScript(jsContentStr1,{
    range: true,
    tokens: true,
    comment: true
}).body;


let tree = esprima.parseScript(jsContentStr1,{
    range: true,
    tokens: true,
    comment: true
});
tree = escodegen.attachComments(tree, tree.comments, tree.tokens);
escodegen.generate(tree.body[0],{comment:true})
