The concat()
method combines the text of two or more strings and returns a new string.
str.concat(string2, string3[, ..., stringN])
string2...stringN
The concat()
function combines the text from one or more strings and returns a new string. Changes to the text in one string do not affect the other string.
concat()
The following example combines strings into a new string.
var hello = 'Hello, '; console.log(hello.concat('Kevin', ' have a nice day.')); /* Hello, Kevin have a nice day. */
It is strongly recommended that assignment operators (+
, +=
) are used instead of the concat()
method. See this perfomance test.
