How to make a function that find the uppercase in a string and add a space

How do i make it so the function will take in the param (breed) and search the uppercase letter and add a space there.

for example if i pass "goldenRetriever" as the param, then the function will transform it into "golden retriever"

function test(breed){
    for(i=1; i<breed.length; i++){
    //wat do i do here
    }
}

You could split the string before each uppercase letter using a regular expression with a positive lookahead, /(?=[A-Z])/, then you could join the string back together with a space and convert it to lowercase:

"goldenRetrieverDog".split(/(?=[A-Z])/).join(' ').toLowerCase();
// "golden retriever dog"

Alternatively, you could also use the .replace() method to add a space before each capital letter and then convert the string to lowercase:

"goldenRetrieverDog".replace(/([A-Z])/g, " $1").toLowerCase();
// "golden retriever dog"
