  The lack of a standard library in JavaScript hampers productivity and restricts its application potential. Implementing common utilities and data structures from scratch is time-consuming and error-prone. Finding suitable libraries on npm is tedious due to the abundance of low-quality options. Moreover, the absence of a comprehensive standard library hinders developers' understanding of algorithms and data structures. Inefficient coding practices, like array manipulation and bubble sorting, are prevalent. A well-maintained standard library would enhance knowledge, promote efficient programming, and fulfill the need for essential functions and algorithms in JavaScript applications.
