ECMAScript standard

The ECMAScript standard is a set of rules that define how programming languages like JavaScript work. It ensures consistency across different environments, so code written under this standard behaves the same way in various browsers and platforms. Essentially, it provides a blueprint for language features, syntax, and behavior, enabling developers to write reliable and interoperable code. By adhering to ECMAScript, programming languages can evolve with new features while maintaining compatibility and predictability across different systems.
