Stop Using any Type in TypeScript
<p>TypeScript is one of the most used programming languages among web developers. It has fantastic language features and allows you to design scalable applications easily. Hence, developers tend to choose TypeScript over JavaScript for their projects.</p>
<p>However, there are some common mistakes we need to avoid when using TypeScript to get the maximum from its features. For example, overusing <code>any</code> type is a common mistake we often make. Although it sounds simple, overusing <code>any</code> type can completely violate the fundamentals of TypeScript.</p>
<p>So, in this article, I will discuss the issue of overusing <code>any</code> type, alternatives for <code>any</code> type and when we should and should not use <code>any</code> type to give you a better understanding.</p>
<h1>What is any Type in TypeScript?</h1>
<p>When you define a variable in TypeScript, you must explicitly tell the type of variable. For example, if you use <code>string</code> as the data type, TypeScript understands that the variable can only have string values. TypeScript will show an error if you try to assign a different type of value for the variable.</p>
<p>For example, the code snippet below will give you the error that <code>Type 'number' is not assignable to type 'string'</code>.</p>
