Node Version Manager (https://github.com/nvm-sh/nvm) works perfectly across native node installations as well as emulated Rosetta installations. The trick I am using here is to install one LTS version of node under Rosetta and another stable version as native binary.

Vue.js is an amazing framework, which can be as powerful as Angular or React, the two big heavy hitters in the world of front-end frameworks.
However, most of Vue's ease-of-use is due to the use of Observables - a pattern that triggers re-renders and other function calls with the reassignment of a variable.
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

| This helper allows you to use generic javascript expressions in a handlebars template. It can be used to call Javascript functions on a value or do data structure access that Handlebars doesn't support (e.g. accessing an element of an array). |

| Is true | |
| {{else}} | |
| Is false | |
