Editor to share with you whether javascript is a dynamic weak language, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. Javascript is a dynamic weak language, a literal scripting language, a dynamically typed, weakly typed, prototype-based language.

2. Data types can be ignored in javascript.

When assigning a value to a variable, you don't need to consider its type; you don't have a type until the variable is assigned a value.

What are statically typed languages and dynamically typed languages?

Programming languages can be divided into two categories according to data types, one is statically typed language, the other is dynamically typed language.

A statically typed language determines the type of a variable at compile time, while a dynamically typed language does not have a type until the variable is assigned a value when the program is running.

In JavaScript, when assigning a value to a variable, you don't need to consider its type, so JavaScript is a typical dynamically typed language.

Advantages of dynamically typed languages:

Less code is written and looks more concise, so programmers can focus more on business logic. Although not distinguishing types can make a program difficult to understand in some cases, on the whole, the less code and the more focused on logical expression, the more helpful it is to read the program.
