Types & Conditionals:
- If, else if or else -> as usual
- Switch (something) {case break and default}: can be more useful
- Primitive types (string, number, boolean, undefined, null & symbol) or Object (everything else). We can look for type with
typeof - explicit type conversion (with functions) or implicit (automatic // coercion)
- In conditionality, java script will convert to boolean. All value will be "truthy" (coercion to true) and "falsy" (coercion to false). Remember that: "false", "0", " '' " (empty), "null", "undefined" and "NaN" are the falsy values.
- For direct comparison, we need to use
===as other equals change types. And avoid direct comparison (=) - Ternaries do not allow actions. They are nice with value assignment with conditionals
-
&&has higher precedent than||, unless we are using()
