看懂代码。知识记载和掌握是两回事,不是抄书匠,要理解消化知识。

day20201222做一行爱一行。学习模仿++解决问题。
摘抄

其实不管是前端还是后端或是其他职业,都有感觉到吃力的时候。之所以吃力是因为不会,而又急需短时间去学会去运用。
不会那就学。你说你用心学了还是没进步,那要反省下,自己真的用心了吗?学习的方法是不是不对?用心靠自己,方法因人而异。我说下我的方法:
1、模仿。问题中你也说到模仿,这是很好的学习方法。你现在用的vue也是模仿+创新。飞机模仿鸟,雷达模仿蝙蝠;百度模仿Google,京东模仿淘宝;我们小时候说话也是模仿大人。模仿是快速习得新事物的方法。模仿不是照抄,而是模仿时要去思考,为什么这样做,能用其他方式吗,哪种方式比较好,好在哪。
2、多实践。我觉得你现在的问题可能就是因为写的太少。你负责写页面比较多,所以你要刻意练习,多写js,模仿别人代码不要复制,要一个字母一个字母敲。
3、关注解决问题。初学者不用一开始就想着怎么优化代码,先关注问题如何解决,不管代码写的多丑,尽管写,先满足需求再考虑优化。学习是为了解决问题的,形式再好,解决不了问题都是瞎扯。
总结,学习=模仿+练习+解决问题。
最后,心态很重要,接受自己是个普通人,接受自己现在能力不够,不要给自己太大压力,压力太大会限制思考。
方法有了,心态放好,要对自己有信心,只要是智商正常的普通人,没有学不会的,加油。

每天的目标能讲解说出个所以然。
程序=数据结构+算法分析。
差等生,因为努力不够。所以努力才能变成心中尊重的自己的样子。
落落大方很重要。阳光正能量,好好读书好好学习好好工作,人生重要的事情没有那么多。有信仰,党的精神。
学习的过程是连续的,保持学习的习惯。
Q:为什么热爱做编程?
拿出上班的状态,好好学,就不会有问题。
借住在父母家,所以自己要找事情做,好好挣钱。价格价值。
忌 玩物丧志。相信自己配得上世间所有的美好,并追求为之而努力是最重要的。认真专心一个时间段做好一件事情。不能闲着,找事情做。就做这件事情。和考试一样,这2小时你就做这个试卷其他的事情不用做。做事冲动想做就做的人,比犹豫的人更好。因为多尝试更多机会。没有后悔药,少壮不努力,老大徒伤悲。珍惜时间,不要等老了再后悔,不要做这样的啥事情。步步高学习机,Diana powerful。讲明白的过程。学习成长,之后很多年都是做这样的事情。少壮不努力,老大徒伤悲。不懂不会别怕,学。不要无知不要肤浅。时间功夫花在哪里,哪里就会有回报。花了时间金钱就不能白费浪费,要珍惜时间学seize the time.
当日事当日毕。
