— The MAIN difference is readFile vs readFileSync

—

But for effective prupouses this is the equivalent?

new Promise((resolve, reject) => {
    process.nextTick(() => {
        console.log("Then run");
        resolve()
    })
})
console.log("Running loop");
for(var i = 0; i < 100; i++) {
    console.log("Blocking");
};

— No

— I really want to understand this

— This?

new Promise((resolve, reject) => {
    setImmediate(() => {
        console.log("Then run");
        resolve()
    })
})
console.log("Running loop");
for(var i = 0; i < 100; i++) {
    console.log("Blocking");
};

new Promise(function (resolve, reject) {

    resolve("Hello World");

}).then(function (data) {

    console.log(data); // "Hello World!"

}).catch(function (exception) {

    console.error(exception);

}).then(function (data) {

    // This runs on both resolve & reject

});

— Ok, I'm back

— Are you using node promises?

— Yes

— Me?

— I was referring to just the plain jane js promises which differ a few ways

— Lmao, I tried this, and it blocked right away.

new Promise((resolve, reject) => {
    while(true);
})
console.log('Then')
setTimeout(() => console.log('Time is out'), 100)
