Similarities between javascript and c languages
Some words and grammar are the same. JavaScript's lexical grammar is designed with reference to Java, while Java's lexical grammar is designed with reference to C. JavaScript, Java, C++ and C all share the same morphology and grammar that I can think of:
Use a single equal sign as an assignment operator rather than an equality judgment operator, for example: a=b+1 stands for "assigning the result of variable BF1 to variable a" rather than "the value of variable an is equal to the value of variable BF1"
Assignment is an expression that can be used as a value to participate in other operations, such as: (a=b+1) > 10
Statement ends with a semicolon
Start with "0x" to represent a hexadecimal number
Use "&" | ^ ""! "& &" | | "as the operators of bitwise and, bitwise OR, bitwise XOR, logical non, logical and, logical or operation, respectively.
A ternary operator consisting of a question mark and a colon
Precedence order of multiplication and division operators, addition and subtraction operators, comparison operators, logic and logic or operators, assignment operators
The syntax of a function call is "function name (parameter 1, parameter 2,.)"
Put the code block in curly braces
Syntax of if, for, while, do-while, switch-case, break
