JavaScript-based web application frameworks, such as React and Vue, provide extensive capabilities but come with associated trade-offs. These frameworks often extend or enhance features available through native web technologies, such as routing, component-based development, and state management.
Front-end web development – the practice of converting data to a graphical interface, through the use of HTML, CSS, and JavaScript, so that users can view and interact with that data.

Line vs. block – a line comment starts with a delimiter and continues to the end of the line (newline marker) whereas a block comment starts with one delimiter and ends with another and can cross lines; Nestable – whether a block comment can be inside another block comment
JavaScript is weakly typed, which means certain types are implicitly cast depending on the operation used. [59] The binary + operator casts both operands to a string unless both operands are numbers. This is because the addition operator doubles as a concatenation operator; The binary -operator always casts both operands to a number
