decodeURI not fully working

the url looks as it was encoded twice, I also suggest to use decodeURIComponent

decodeURIComponent(decodeURIComponent("http%253a%252f%252fsandbox.yoyogames.com%252fgames%252f171985-h-a-m-heroic-armies-marching"))

results in: "http://sandbox.yoyogames.com/games/171985-h-a-m-heroic-armies-marching"

but you should check why you have the url encoded twice in advance

My implementation is a recursive function:

export function tryDecodeURLComponent(str: string, maxInterations = 30, iterations = 0): string {
    if (iterations >= maxInterations) {
        return str;
    } else if (typeof str === 'string' && (str.indexOf('%3D') !== -1 || str.indexOf('%25') !== -1)) {
        return tryDecodeURLComponent(decodeURIComponent(str), maxInterations, iterations + 1)
    }

    return decodeURIComponent(str);
}

• str: encoded string.
• maxInterations: Maximum recursive iterations to try decoding str (default: 30).
• iterations: Flag counter iteration.
