404Errors can be written like this
ErrorDocument code error.php
If it’s 404 error, jump to file error. PHP
Other common error page writings (of which 404 errors have two writings, the one above and the one below are generic error definitions)
ErrorDocument 404 /error/404.php
ErrorDocument 500 /error/500.php
ErrorDocument 400 /error/400.php
ErrorDocument 401 /error/401.php
ErrorDocument 403 /error/403.php
ErrorDocument 503 /error/503.php
If it’s a 404 error, jump to the 404. PHP file in the error directory

Use this attribute to be an optional attribute.
interface BaseButtonProps {

}
generic type
Let’s look at the following simple generics.
function greetNane<T>(name:T):T{
return name
}
let myIdentity: <T>(name: T) => T = greetNane;
We can also define the generic function using the literal size of the object with the calling signature.
function greetNane<T>(name:T):T{
return name
}
let myIdentity: {<T>(name: T): T} = greetNane;
This leads us to write the first generic interface. We take the font size of the object i...
LeetCode：Summary interval [228]
Title Description
Given an array of ordered integers without repeating elements, returns the sum of the array interval ranges.
Example 1:
Input: [0,1,2,4,5,7]
Output: ["0->2","4->5","7"]
Explanation:0,1,2 It can form a continuous interval, and 4,5 can form a continuous interval.
Example 2:
Input: [0,2,3,4,6,8,9]
Output: ["0","2->4","6","8->9"]
Explanation:2,3,4 It can form a continuous interval, and 8,9 can form a continuous interval.

Core: a book reading chip industry
The author attempts to introduce the history of the chip industry in the past 60 years. The book contains 4 chapters, and the first chapter is not bad. It introduces the major events and some key technical details of the chip industry. Most of the events have been seen many times in other materials. Some technical details are for the first time, such as optical lithography.
The latter 3 chapters are stacked in many industry materials and public relations manuscripts, and I feel dull during my reading.
In the later order, the author said that the book was wr...
