A regex cheatsheet 👩🏻‍💻 (by Catherine)
let regex;
/* matching a specific string */
regex = /hello/; // looks for the string between the forward slashes (case-sensitive)... matches "hello", "hello123", "123hello123", "123hello"; doesn't match for "hell0", "Hello"
regex = /hello/i; // looks for the string between the forward slashes (case-insensitive)... matches "hello", "HelLo", "123HelLO"
regex = /hello/g; // looks for multiple occurrences of string between the forward slashes...
/* wildcards */
regex = /h.llo/; // the "." matches any one character other than a new line character... matches "hello", "hallo" but not "h\nllo"
regex = /h.*llo/; // the "*" matches any character(s) zero or more times... matches "hello", "heeeeeello", "hllo", "hwarwareallo"

Setting the current date and time on a HTML5 date or datetime field with Javascript

Setting the current date and time on a HTML5 date or datetime field with Javascript

By default date.toISOString returns UTC time instead of local time. So you'll need to calculate the timezone offset first.

//Get the local date in ISO format
var date = new Date();
date.setMinutes(date.getMinutes() - date.getTimezoneOffset());
var datestr = date.toISOString().substring(0, 10);

Wait until all promises have completed even when some reject, with Promise.all
var a = ["sdfdf", "http://oooooolol"],
handleNetErr = function(e) { return e };
Promise.all(fetch('sdfdsf').catch(handleNetErr), fetch('http://invalidurl').catch(handleNetErr))
.then(function(sdf, invalid) {
console.log(sdf, invalid) // [Response, TypeError]
})
.catch(function(err) {
console.log(err);
})
