First, become familiar with the language by reading through tutorials and studying the syntax. Knowing basic concepts such as variables, functions, and control structures can help make programming much easier.
Additionally, when writing code, be sure to comment throughout to help keep track of which parts of the program are working properly and which need debugging. It may be beneficial to use the help of a code editor, as this will provide helpful syntax highlighting and code completion.
Finally, make sure to test the code before running a program. This can help to locate any errors, as well as identify
As an example, find the code below:
Access the file through your preferred internet browser to view the result in a dialogue window.
Use the console to test the code
The console within the browser’s development tools can be accessed by entering a series of instructions. To display the development tools, use the menu option or keyboard shortcut (for many browsers, this is the F12 key, Ctrl+Alt+I, or, on Mac, Cmd+Option+I).
For longer code sequences, it is recommended to store the instructions in a file and use the console.log method to generate output. As an example, the instructions can be placed in the file index.js:
let a = 6 let b = 7 console.log(a * b)
Utilize debugging tools
Type commands into the terminal to view the corresponding results,
Next, execute the command.
The result of the console.log command will be displayed in the terminal.
