This article mainly introduces the performance of js concatenating string arrays. String connection has always been one of the operations with the lowest performance in js. How can this problem be solved? Please refer to the introduction in this article and we know that in js, string connection is one of the operations with the lowest performance. For example:

Traditionally, string connection has always been one of the operations with the lowest performance in Js. VaRText="Hello";Text+ ="World!"; Early browsers did not optimize this operation. Because the string is immutable, this means that you need to create an intermediate string to store the connection results. Frequent background creation and destruction of

The array class can be defined as follows:var avalues = new Array ();If you know the length of the array beforehand, you can pass the length with the parametervar avalues = new Array (20);------------------the following 2 ways to define the same--------1-----------var acolors = new

The array class can be defined as follows: VaR avalues = new array (); If you know the length of the array in advance, you can use the parameter to pass the length VaR avalues = new array (20 ); ------------------ The following two definitions are the same -------- 1 ----------- VaR acolors = new
