核心提示：1、同步：var fs = require(fs);console.log($file starting...);var content = fs.readFileSync(fileTest.txt,...
1、同步：
var fs = require('fs');
console.log('$file starting...');
var content = fs.readFileSync('fileTest.txt','utf-8');
console.log(content);
2、异步：
var fs = require("fs");
fs.readFile("fileTest.txt",'utf-8',function(err,data){
if(err){
console.log("error");
}else{
console.log(data);
}
});
console.log("Read file async end!");
