Assignment
- Open the developer tools console in your browser Console as explained in section Tools for Developing in Javascript of this tutorial.
- Clear the console by clicking the appropriate icon ('bin' in Firefox or 'forbidden' in Chrome).
- Do not close the Console until you have finished the work and exported it (instructions for this at the end).
- Open this tutorial at section Javascript Operators.
- In the Console, write and run code to complete the following tasks.
- Apply operator + to two numbers.
- Apply operator + to a string and a number.
- Apply operator + to two strings.
- Apply operator == to a string and a number, so that the expression evaluates to true.
- Apply operator === to any two operands, so that the expression evaluates to true.
- Apply operator < to two strings, so that the expression evaluates to true.
- Apply operator && to any two operands, so that the expression evaluates to true.
- Apply operator ! to any expression, so that the operation evaluates to false.
- For each type (number, string and boolean), apply operator typeof twice: once on a literal value of that type and once with a complex expression that yields that type.
- Apply the indexing operator ([]) to extract the first, the second last and the last character from string "TUDublin" and the concatenation opearator (+) to string them together (you should get "Tin" as a result). Be careful with the index ("TUDublin"[0] gives the first character, "TUDublin"[1] gives the second character etc.).
- Execute one example of using the function alert() and one example of using console.log().
- Export the console contents to a file:
- In Firefox: right-click on any message in the console, click Export visible messages to file, click File, use dialogue to save a file
- In Chrome: right-click anywhere in the console, click Save as, use dialogue to save a file
- Submit the created file by adding it to your lab GitHub repository.
