How to learn front-end js

The first thing to explain is that we are not experts now. At most, we are still half a bucket of water. We have just entered the JS door. It’s not about experience, it’s just lessons learned.

At this time, someone will say, "Damn, why are you teaching us with half a bucket of water?" Don't rush to scold me, just listen to me first.

If you ask a college student to teach primary school mathematics, he may not be able to teach it better than a junior high school student. Because college students have already passed that stage and have forgotten how they got there. For junior high school students, who have just passed that stage, they still have fresh memories of how they got there, or they may have some conclusions of their own. For example, many experts think that the Rhinoceros book is a good way to get started. They think it is too simple, but from my experience, it is not the best choice for getting started.

Let’s talk about the conditions for learning js first

As for the conditions, I am a liberal arts student, majoring in business administration at university, and have nothing to do with computers; some people speak English and read After four years of college, it’s a pity that we haven’t passed Level 4 yet.

Of course there are thresholds for learning JS, that is, you are at least relatively proficient in html and css. You cannot start learning JS without even knowing what the thing is for. Learn multiplication and division. Before, it was always beneficial to learn addition and subtraction.

A few more words of advice

2, don’t rush to join QQ group for technical exchanges, add talented people on QQ. If you go to Zhang Sanfeng to exchange martial arts, and the first thing you ask is "Brother Feng, where is Dantian?", you will be struck to death by his palm.

3. Look at the Internet and see how many days it takes to become proficient in JS. From getting started to being proficient in anything, just skip this kind of tutorial. Too many facts have proved that doing anything with an impetuous mentality will lead to failure. ended in failure.

4. Don’t get any computer training. Not to mention the money and time spent, the key is that you won’t learn anything. Originally, you could learn it by buying two good books and studying on your own in three months, but they can force you to do it for two years.
