How to loop all the elements that match the regex?

Question

Here is the case: I want to find the elements which match the regex...

targetText = \"SomeT1extSomeT2extSomeT3extSomeT4extSomeT5extSomeT6ext\"

Answer 1

I kept getting infinite loops while following the advice above, for example:

var reg = /e(.*?)e/g;
var result;
while((result = reg.exec(targetText)) !== null) {
    doSomethingWith(result);
}

The object that was assigned to result each time was:

["", "", index: 50, input: "target text", groups: undefined]

So in my case I edited the above code to:

const reg = /e(.*?)e/g;
let result = reg.exec(targetText);
while(result[0] !== "") {
    doSomethingWith(result);
    result = reg.exec(targetText);
}
