The first method is the well-known concat, but this method has a confirmation that this method will not change the existing array, but will only return a copy of the connected array.If we only want to add the elements of a new array to the existing array, We need to assign a new value to it. In fact, there is a waste of resources. To put it simply, we need to allocate new memory space for the newly created array and point arr1 back to the new memory a

The Concat () method of an array presumably everyone is stranger than, in this article to introduce the JavaScript in the array of concat () method of specific use, interested friends can refer to theThe code is as follows:

select concat(‘grant all on ‘, table_schema,".",table_name," to ‘ gxsnerp‘@‘localhost ‘;") from tables where table_schema=‘gxsnerp‘ and table_name like ‘ACT%‘;The generated stitching statements are as follows:Grant all on Gxsnerp. Act_hi_varinst ' to ' gxsnerp ' @ ' localhost ';Grant all on Gxsnerp. Act_ge_property to ' gxsnerp ' @ ' localhost ';Grant all on Gxsnerp.

This article mainly introduces how to use concat to connect multiple arrays in Javascript. The first method is the well-known concat, however, this method has a confirmation that it will not change the existing array, but will only return a copy of the connected array. If we only want to add the elements of a new array to the existing array, We need to assign a new value to it. In fact, there is a waste

If you want to convert the dom set obtained through getElementsByTagName to a real array, you may not understand the result (different from what you expected). The test code is as follows: runjs. cncodei517birf wants to convert the dom set obtained through getElementsByTagName into a real array, which is a bit confusing for their results (different from what they expected). The test code is as follows: Http://runjs.cn/code/i517birf Reply content: The test code is as follows:Http://runjs.cn/

Simple stream file merging can be implemented using FFmpeg's concat. For example: ./ffmpeg-i concat: "Out002.ts|out003.ts|out004.ts"-acodec copy-vcodec copy-f mp4 cat.mp4 Note: Each stream you enter requires a consistent encoding parameter, otherwise the output file will be different than expected. Data reference: Physical concatenation protocol. Allow to read and seek from many resource in sequence as if
