5 recommended articles about front-end programmers
Summary of a JavaScript interview question that many front-end programmers often ignore: Preface I just resigned a few years ago. Let me share an interview question I once asked. This question is the last one in a set of front-end interview questions I asked. This question is used to test the interviewer's comprehensive ability in JavaScript. Unfortunately, in the past two years so far, almost no one has been able to answer it completely. It is not that it is difficult but because most interviewers underestimate him. The title is as follows: function Foo() { GetName = function () { alert (1); }; Return this; } Foo.getName = function () { alert (2);}; Foo.p
1. A summary of a JavaScript interview question that many front-end programmers often overlook
Introduction: Preface I just resigned a few years ago. Let me share an interview question I once asked. This question is the last question in a set of front-end interview questions I asked for assessment. Regarding the interviewer’s comprehensive ability in JavaScript, it’s a pity that in the past two years so far, almost no one has been able to answer it completely. It’s not that it’s difficult, it’s just because most interviewers underestimate him. The title is as follows: function Foo() { getName = function () { alert (1); }; return this; } Foo.getName = fun..

4. How do front-end programmers deal with the provocation of PHP back-end programmers?
Introduction: I was fired from the company today because I got angry during a meeting and scolded PHP. Because the company is relatively small, there are two backends, me on the frontend, and an artist. The thing is like this, during the meeting, the PHP programmer kept pushing me. After talking about the front-end, he talked about the back-end, and after talking about the front-end, he talked about the art. The idiot boss didn't understand anything and was fooled by him. I was stunned for a while, leaving me and the artist. It’s worthless. For example, “Isn’t the front-end just a DIV? It’s a simple thing.”, “If you want me to write it, I can write it myself. Make it simpler.” "You have to work hard on this color"
Introduction: Personally, For web front-end programmers and people who work with HTML and CSS, jQuery is the greatest invention ever. The emergence of jQuery has made Web programmers' development efficiency improve by leaps and bounds, which is no less than the improvement brought to human productivity by the industrial revolution. But the problem is that only front-end programmers can take advantage of the power of jQuery, and they can use it to analyze HTML

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.
