Other operators and syntax

There are a few remaining operators and pieces of syntax that we have yet to explore and that don't fall into any other operator category:

• The delete operator: delete VALUE
• The void operator: void VALUE
• The new operator: new VALUE
• Spread syntax: ... VALUE
• Grouping: (VALUE)
• The comma operator: VALUE, VALUE, ...

The delete operator

The delete operator can be used to remove properties from objects, as such its only operand usually takes the form of a property accessor, like so:

delete object.property;
delete object[property];

Only properties that are deemed configurable can be deleted in this manner. All properties added conventionally are, by default, configurable and can, therefore, be deleted...
