First up, the “??” uperator. You’ll probably suspect that this is related to the ?= ternary operator, and you’d be right. The ?? operator is called the null-coalescing operator<\/a>. Not a very meaningful name, but here’s what it does.<\/p>\n

<\/div><\/td>
foo =<\/span> bar ??<\/span> baz;<\/span><\/div><\/td><\/tr><\/tbody><\/table><\/div>\n

<\/div><\/td>
foo =<\/span> (<\/span>bar !<\/span>=<\/span> null)<\/span> ?<\/span> bar :<\/span> baz;<\/span><\/div><\/td><\/tr><\/tbody><\/table><\/div>\n

Also discovered recently: extension methods<\/a>. Not having private access is a bit of a drawback, though I can certainly understand why that is. It amounts to a convenient way to write helper code for awkward APIs.<\/p>\n","protected":false},"excerpt":{"rendered":"
