JavaScript Review

Technology C++, Cheat Sheet, JavaScript, Study Add Comment (1)

In a previous post, (JavaScript != Java)… I had covered what JavaScript can do for a webpage and thanks to a great comment from @apexsutherland I now know the answers to the questions that I posed. Thanks again Alex! This post will be brief and cover the syntax of JavaScript.

I have started the book on C++ and that has greatly helped with my understanding of JavaScript (FYI: I will be posting again about the start of the C++ book and probably more on JavaScript as I learn more). Syntax to remember:

• Composed of statements that end can end with a ; or a line break
• Be mindful of capitalization because it is a case-sensitive language
• Single line comments start with //
• Multiple line comments start with /* and end with */
• Read the “=” as “is set to”
• Example : if (test condition) {value if true; value if false;} Note: does not have to have a value for a false return. Note: This is helpful for making sure web-to lead forms are completely and correctly filled out
• I need more time before I completely understand arrays – I see how they are set-up and know they are very important (saw them in action at Dreamforce with help from @jhoskins). Any suggestions?

To me, the syntax seemed very similar to C++. Now that I have started to learn about C++ it is greatly helping my comprehension of JavaScript and vice-versa for that matter! I am hoping it will help with arrays!
