TypeScript improves the development experience by offering better tooling support and early error detection with the introduction of static typing. <\/p><h3 class=\"wp-block-heading\">Types of TypeScript:<\/h3><p>TypeScript has more types than just the ones in JavaScript. Some of these are:<\/p><ol class=\"wp-block-list\"><li><strong><em>Any:<\/em><\/strong> The Any type lets you work with JavaScript code that is already there. Developers can use it to slowly turn off and on type checking while the code is being compiled.<\/li>\n\n<li><em><strong>Enum:<\/strong><\/em> You can use enum to give sets of numbers nicer names. One way to name a group of colors with Enum is &#8220;color.&#8221;<\/li>\n\n<li><strong><em>Void:<\/em><\/strong> Not any of those things, Void is the lack of anything. Many methods that don&#8217;t return a value will use &#8220;void&#8221; as their return type.<\/li>\n\n<li><strong><em>Tuple:<\/em><\/strong> Developers can explain an array with a set number of elements that have known types that might not be the same using Tuple types.<\/li>\n\n<li><strong><em>Never:<\/em><\/strong> This kind of value is for values that never happen. As an example, the return type of an arrow function expression that never comes back is Never.<\/li>\n\n<li><strong><em>Type assertions:<\/em><\/strong> Developers are not always as knowledgeable about a value as TypeScript is. To inform the TypeScript compiler that they have already completed the required checks, they can utilize type assertions.<\/li>\n\n<li><em><strong>Union:<\/strong><\/em> Two or more other types can be combined to produce a union type.
