👉 The Intl.Fluid property in JavaScript's Internationalization API is used to specify the fluidity or adaptability of a string when it needs to be translated into different languages. This property allows developers to define how text should adjust its width and layout when translated, accommodating variations in character sets and sentence structures across languages. By setting a value between 0 (fixed width) and 1 (fluid width), developers can control whether the text will stretch or remain fixed in size, ensuring that the translated content fits well within its container without breaking the layout. This feature is particularly useful for creating responsive and user-friendly applications that need to support multiple languages with varying text lengths.
