odd results from nested for loops javascript

Question:

Tag: javascript,arrays,sorting,object

I'm trying to check a submitted string against a letterset. If word_string = "GAR", this should return "GAR" because these letters appear in letterset.

For some reason, some words appear correctly, and some appear with missing letters. For example, with word_string = "RAG", this returns "R". "FIG" returns "FG".

letterset = {0: "R", 1: "A", 2: "G", 3: "A", 4: "O", 5: "E", 6: "F", 7: "I"}


    var ls = [];
    for (prop in letterset) {
        ls.push(letterset[prop]);

    };
    console.log(ls)
    var word_string = '';
    var word = document
               .getElementById('word_container')
               .childNodes;
    for (var i in word) {
        var w = word[i].innerHTML;

        for (var prop=0; prop<ls.length; prop++) {
            if (ls[prop] == w) {
                console.log(w);
                word_string += w;
                ls.splice(prop);

            } 
        }

}

Answer:

I think you are using splice incorrectly, regardless this is a bit over complicated try:

 for (var i in word) {
    var w = word[i].innerHTML;
    if (ls.indexOf(w)> -1) {
            word_string += w;
        } 
    }
