Stack on Javascript path

Hi all ,i am Michael . I am totally lost when i try this section "Basic Algorithm Scripting " .I try the next section "Object oriented programming " and it was very easy . So… is it the sections in the right order? Does anyone found the Basic Algorithm section difficult? What else can i read before try it again ?

algorithms are hard, and need a bit of effort, or a lot, they requires also a lot of logical effort.

what you can do to practice is try with pseudocode, as in, try to write a sequence of actions in plain english (or whatever human language) that would bring from the input to the output
only once you have a working algorithm you would then translate in in javascript


i got the point . Thank you very much for your time . It’s a logical operator i suppose
