not weird at all - JavaScript is a practical thing to learn.
I would focus on learning concepts that apply to all programming languages and then you’ll see where the differences occur. Loops, assigning variables and using them, booleans, these are all useful.
Where JavaScript would be a bad ‘starter’ language will be if you get into lower level things like C where memory must be allocated before using. Java (different from JavaScript) is a little easier than C since it takes care of that, but is very strict on data types (is this a string or number/what kind of number is this/does it have a decimal point? etc). Some languages don’t care and adjust for you (JavaScript, Python). Haven’t learned Lua myself, but it looks nifty.
