SCSS syntax resembles more like a CSS syntax but SASS syntax is little bit different from SCSS but both produces exactly the same CSS code.SASS we are not ending the style properties with semicolon(;) but in SCSS we are ending the style properties with (;).SCSS we used paranthesis {} to close the style properties but in SASS we don't use paranthesis.Indentation is very important in SASS. It will define the nested properties in the class or id of the element.scss we can define multiple variables in single line but in SASS we can't do.
