learn basics web end knowledge

In the past, developers only needed to master HTML、CSS、JavaScript The troika can do a front-end job . Now in addition to ordinary coding , Also consider how to optimize performance , How to cross ends 、 Cross platform implementation , In especial AI、5G The advent of Technology , Are speeding up the update of front-end technology , It also forces developers to keep learning , Can't accept new technical standards .

“ What to learn ”“ How to learn ” In fact, it's the problem we should focus on . therefore , Today, I'd like to give you an overview of the front-end knowledge framework , Help you to traverse the knowledge points again , It's easier to check the gaps and make up for them .

Let's first look at what is knowledge architecture ?

We can understand it as knowledge “ Catalog ” Or index , It can help us organize the scattered knowledge , It can also help us find some knowledge blind spots .

This article contains JavaScript、CSS and HTML As well as the implementation principle and API, These three modules cover all the knowledge a front-end engineer needs to master .

JavaScript Knowledge architecture

stay JavaScript In the module , First of all, we can follow the grammar 、 Semantic and runtime to split , This is in line with the general rules of programming languages : With a certain vocabulary and grammar , Express a certain meaning , To operate the runtime .

Runtime can be divided into data structure and algorithm part —— Data structures contain types and instances ( Built-in objects ), The algorithm is the execution process . The execution process should follow the cycle of events and micro tasks from the top level , To the function 、 And then to statement level execution .

Grammar and semantics are basically one-to-one correspondence , stay JavaScript There is a grammar definition table in the standard , I suggest you take it out at any time .

HTML and CSS Knowledge architecture

stay HTML Part of , We divide its knowledge according to function and language ,HTML The function of is mainly carried out by the label , So first of all, we need to classify the labels . Classification after the elements in the figure , It's the different functions we undertake , Divide the labels into several categories .qun:784783012, It's all about learning the front end from the most basic HTML+CSS+JS【 Cool special effects , game , Plug in encapsulation , Design patterns 】 To mobile HTML5 The learning materials of the project and actual combat have been sorted out , To every front-end partner .2019 Latest technology , Synchronization with enterprise requirements

Besides the label , You should also put HTML Understand as a language . More basic HTML Grammar and several important language mechanisms : Entity 、 Namespace , You must master .

CSS part , It can be divided by language and function .

The language part ,@rule、 Selectors 、 Units are three parts to be concerned about .

Function part , You can focus on the layout ( Normal flow and elastic layout )、 draw ( Graphics and text ) And interaction classes .

Browser implementation principle and API

How browsers work , It's our deep understanding of API The basis of

Starting from the general browser design , According to the analysis 、 structure DOM Trees 、 Calculation CSS、 Rendering 、 The process of composition and drawing to learn how browsers work .

stay API part , It can be downloaded from W3C Choose a few large pieces of... From the scattered standards API Let's explain in detail , There are mainly : event 、DOM、CSSOM Several parts , They each cover interactions 、 Semantics and visible effects , This is the main content of our work .
