1. Conditional expressions without parentheses (this is what other languages need to be aware of)

2. Support an initialization expression (can be in parallel, i.e.: A, B, c: = 1, 2, 3)

3. The opening brace must be on the same line as the conditional statement or else

4. Support single-line mode

5. The variable in the initialization statement is the block level, while the external variable with the same name is hidden

The sample code for the IF statement is as follows:

Package Mainimport"FMT"Func Main () {a:=true    ifA, B, c: =1,2,3; A + B + C >6{fmt. Println ("Greater than 6")    } Else{ fmt. Println ("less than or equal to 6") FMT. Println (A)} fmt. Println (a)}

Less than or equal to 61true
