function execute() { 
    var a = 'a' 
} 

// jscodeshift 
export default(file, api) => { 
    const j = api.jscodeshift 
    const root = j(file.source) 

    var node = root.find(j.VariableDeclaration) 
    // i want to see what node looks like in javascript. 

    return root.toSource() 
}

推測有你的搜索內容的一個非空的集合：

var node = root.find(j.VariableDeclaration).at(0).get(); 
// in js node looks like 
return j(node).toSource();
