Hello there, I recently started a web dev course on nodejs courtesy of a collaborative partnership between progate and devcareer for the next 90 days. It's been so thrilling all the way, I now really understood the essence of arrays and objects in programming and why we use call-back functions. So, I will be highlighting what I have learned so far in the program. For context's sake, I had to go through the javascript modules to really refresh and understand the concepts I would be using in time to come. Additionally, I have shared a screenshot of a simple program I wrote to solidify my knowledge of the concepts I have learned.
Lessons
Data structure and Conditionals
- Strings and integers
- Variables and constants
Conditionals (if statement, else, switch etc. )
Iterations (while and for loops)
- Arrays
- Objects
- Undefined
Functions
- Arrow functions
- Argument
- Multiple Arguments
- Return values
- Scope
Array Methods
- push
- forEach
- find
- filter
- map
Callback function
- Declaring callback
- Argument of callback functions
Finally, I wrote a program that utilized most of what l have learned from the progate platform. The program add new applicant's details to the array of objects, prints out some items based on some condition , passes a function as a parameter to another function (callback) etc.
Thank you for reading. I hope to share more of my technical journey. 🙂
