Mad JavaScript!! 😓

Okay I've got experienced in different skills, but JS seems to be a nightmare, especially when working with data types and functions, although I'm trying to become familiar with it. Was this normal for anyone, when you started to go deeply in this CRAZY lang đŸ˜‚đŸ˜©đŸ˜  Need support to gain some more knowledge

It's normal as you'll gradually get used to it. Your programming experience will help you especially if you're from Java. Data types *Number //not integer *String // nothing like 'char' *Object(typeof array is object) *function *Boolean *Date NaN - Not a Number typeof NaN == "number" // true Javascript is crazy.

@wisdom thanks for your response .. But without doubt, you know it's preferred to read some more detailed stuffs, & I will appreciate if you provide me a resource .. or code reviews. To be more specific, I have problems with: - equal: == and === - data types: null, undefined, NaN; Ex: var x=NaN; var y=250; alert(x+y); And other things .. Note that I have completed Sololearn's tutorial, but challenges seems to be from Mars 😅
