Ruby has a .method() call where you can dynamically cal a method from an object. So if @object has @object.foo() and @object.bar() methods you could call @object.method(‘foo’).call etc.

In JavaScript let’s say you have two functions defined the same foo() {} and bar() {} and I have a variable set like var type = ‘foo’. Can you somehow call those functions dynamically from that variable?

Still learning JS so this may be a trivial question but I can’t seem find a quick answer.

Object methods are just properties, so you use `object[type]()` – Barmar Jan 20 '22 at 05:47
The object example was ruby not JS. – Dan Tappin Jan 20 '22 at 16:01
The 'answered' question doesn't answer MY question at all. I ended up with this: https://jsfiddle.net/jasper502/h87urnL2/3/ – Dan Tappin Jan 20 '22 at 16:03
