const fs = require('fs');
fs.readFile(__filename, () => {
process.nextTick((e) => {
console.log(e)
console.error(e)
},new TypeError('argument should be string'))
setImmediate(() => {
console.log('immediate');
});
});
輸出結果如下
TypeError: argument should be string
at D:\projectOther\mylib\src\test.js:7:5
at FSReqCallback.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:63:3)
immediate
TypeError: argument should be string
at D:\projectOther\mylib\src\test.js:7:5
at FSReqCallback.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:63:3)
為什么執行順序是先console.log(e)，然后console.log('immediate')，最后console.error(e)
