A class method, such as Math abs(), is implemented in the same way as a class property — a function is assigned to a property of the constructor function
Statements – Functions - Objects – Array – Strings – Math – Boolean – Global The following code shows how to use arithmetic operators in JavaScript
JavaScript Arithmetic operators JavaScript Assignment operators a = new Array(); months = new (“JAN”, “FEB”, “MAR, “APR”, “MAY, “JUN”, “JUL”, ,
Quelques opérations sur les variables JavaScript Autres opérateurs arithmétiques * : multiplication - : soustraction / : division
Identifiers refer to the name of variables, functions, arrays, etc created These are used to perform arithmetic/mathematical operations like
Fortunately, JavaScript gives us a way to simply ask the array itself, const numberOfPeople = Math floor(100∗Math random ( )
JavaScript prints as Infinity • For more complex math operations than the usual ones we have the Math object // number examples
Object/Array variables are references (Java-like?) ○ Arrays are objects (verify with typeof) Standard function Math abs(), Math floor(), Math round()
Variables A variable in JavaScript can hold one of several data types, including numbers, strings, arrays, booleans, functions, objects, etc
