C, Go, Java and Swift are great examples of strongly typed languages.Being loosely typed doesn’t mean you don’t have types, of course, as you can see in my JavaScript Types post. You just make use of types implicitly, with the pros and cons that you imagine....
In particular, TypeScript is strongly typed—meaning that the programmer can declare variables and other data structures to be of a specific type, like a string or a boolean, and TypeScript will check the validity of their values. This isn’t possible in JavaScript, which is loosely typed. ...
The Syndication object model (SyndicationFeed, SyndicationItem, and related classes) supports loosely-typed access to extension data by using the AttributeExtensions and ElementExtensions properties. This sample shows how to provide strongly-typed access to extension data by implementing custom derived ...
using the dot and an identifier, is like the syntax used to access a staticfield of a struct or object in C or Java. The second syntax, using square brackets and astring, looks like array access, but to an array indexed by strings rather than...

.Since JavaScript is a loosely typed language, this rule does not apply: a program cancreate any number of properties in any object. When you use the . operator to accessa property of an object, however, the name of the property is expressed as an identifier.Identifiers must be typed ...
