Question

What would be the quickest way to remove “everything” from a string, starting from the first “dot”.

For example:

This.Is.A.Test

=> would become

This

Answer 1

You can use the the split() function like this:

"This.Is.A.Test".split(".")[0]; // will work even if there are no dots

Or you could use the substr() function in combination with the indexOf() function, like this:

var myStr = "This.Is.A.Test";
var justTheFirstBit = myStr.substr(0, myStr.indexOf(".")); // needs 1 dot minimum
