JavaScript space-separated string to camelCase

Question

I've seen plenty of easy ways to convert camelCaseNames to camel Case Names, etc. but none on how to convert Sentence case names to sentenceCaseNames. Is there any easy way to do this in JS?

Answer 1

This should do the trick :

function toCamelCase(sentenceCase) {
    var out = "";
    sentenceCase.split(" ").forEach(function (el, idx) {
        var add = el.toLowerCase();
        out += (idx === 0 ? add : add[0].toUpperCase() + add.slice(1));
    });
    return out;
}

Explanation:

• sentenceCase.split(" ") creates and array out of the sentence eg. ["Sentence", "case", "names"]

• forEach loops through each variable in the array

• inside the loop each string is lowercased, then the first letter is uppercased(apart for the first string) and the new string is appended to the out variable which is what the function will eventually return as the result.
