Unexpected tokens (use ‘;’ to separate expressions on the same line)

by

When encountering the error “unexpected tokens (use ‘;’ to separate expressions on the same line)”, it means that there is an issue with the syntax of the code. In many programming languages, including JavaScript, multiple expressions on the same line should be separated by a semicolon ‘;’ character.

Here’s an example to illustrate the error: 

    let a = 5 let b = 10

In this case, the code tries to assign the value 5 to variable ‘a’, but instead of separating the expressions with a semicolon, it directly continues onto the next line to assign the value 10 to variable ‘b’. This leads to the unexpected token error.

To fix this, the code should be modified to use the semicolon properly: 

    let a = 5; let b = 10;

Now, each expression is properly separated by a semicolon, and the error is resolved.
