Clean way to wait for first true returned by Promise

Question

I\'m currently working on something where I fire out three promises in an array. At the moment it looks something like this

var a = await Promise.all([Promis

OK, I will leave the accepted answer as is. But I altered it a little bit for my needs as I thought this one is a little easier to read and understand

const firstTrue = Promises => {
    return new Promise((resolve, reject) => {
        // map each promise. if one resolves to true resolve the returned promise immidately with true
        Promises.map(p => {
            p.then(result => {
                if(result === true){
                    resolve(true);
                    return;
                } 
            });
        });
        // If all promises are resolved and none of it resolved as true, resolve the returned promise with false
        Promise.all(Promises).then(() => {
            resolve(Promises.indexOf(true) !== -1);
        });   
    });    
}
