Just get rid of the parenthesis and that will give you an array with one element and:

• Change this line

var test = tesst.match(/a(.*)j/);

• To this

var test = tesst.match(/a.*j/);

If you add parenthesis the match() function will find two match for you one for whole expression and one for the expression inside the parenthesis

• Also according to developer.mozilla.org docs :

If you only want the first match found, you might want to use RegExp.exec() instead.

You can use the below code:

RegExp(/a.*j/).exec("afskfsd33j")
