Difference between split and join in javaScript (detailed description), splitjoin

Common features: the split and join functions are usually operations on characters or strings;

Differences between the two:

(1) split () is used to split a string and return an array,

For example

Var string = "hello world? Name = xiaobai ";

Var splitString = string. split ("? ");

Console. log (splitString); // ["hello world", "name = xiaobai"]

Split () has only one parameter: The split string or regular expression. When two parameters are used, the second parameter indicates the number of elements in the returned array;

(2) join () is used to connect multiple characters or strings. the return value is a string;

For example

Var arr = new Array ();

Arr [0] = "hello ";

Arr [1] = "xiao ";

Arr [2] = "bai ";

Arr. join ("&"); // "hello & xiao & bai"

Join (); // The default Delimiter is comma;
