If you're lazy loading images, this will prevent the flash of alt text that appears before the images are loaded.
img:not([src]) {
visibility: hidden;
}
/* IE/Edge */
img[data-src]:not([src]),
img[data-srcset]:not([src]) {
display: block;
min-height: 1px;
}

jQuery.event.special.touchstart = {
setup: function( _, ns, handle ){
if ( ns.includes("noPreventDefault") ) {
this.addEventListener("touchstart", handle, { passive: false });
} else {

danfoust / string-keys.type.ts
Created April 8, 2022 15:11
Narrow string | number union with utility type
/*
If you try to do `keyof SomeType`, and `SomeType` has an interface of `[key: string]: x`
TypeScript will infer that to a union of `string | number` because JavaScript coerces numeric
indexes to strings.
Example: obj[0] -> obj["0"]
This can make it annoying to try to create an interface for interacting with one of these
types when we know we only want to accept string values, or that's a rule we want to enforce.
