Well-informed statements written in JavaScript end with what symbol?

In JavaScript, well-informed statements are typically concluded with a semi-colon. This is crucial because the semi-colon acts as a statement terminator, signaling the end of one instruction and the beginning of another. While JavaScript does have a feature called Automatic Semicolon Insertion, which can sometimes allow scripts to work without explicitly placing semi-colons at the end of statements, it is still considered good practice to use them. By doing so, it helps avoid potential issues and makes the code clearer and easier to read.

For instance, if you have a sequence of variable declarations or function calls, placing a semi-colon at the end of each ensures that each statement is interpreted correctly, preventing the risk of errors that can occur due to ambiguous code execution. Thus, the semi-colon is fundamental in maintaining proper syntax within JavaScript programming.
