The expression can be a variable an operator or a function call that has a value. A JavaScript program consists of the following parts sentences operators clauses JavaScript Syntax Example A variable is defined with the keyword var. Here it is given the values x y z x set value to variable x y set value to variable y z x Y calculate the values z Output JavaScript variables In programming variables are data storage locations where only values of the defined type can be stored. A JavaScript variable is a memory location where a program can store the information it needs. They are named with the var keyword. Characteristics of variables Various data values letters or numbers are stored in JavaScript variables.
Data types are numbers strings and Boolean Brazil Mobile Number List logic true or false JS variables are introduced created with the var keyword var keyword. Here the variable name is var Name The variable is set to the value var Lisa A value can also be set for the variable after the definition var Name Liisa Several variables can be defined in one sentence var Name Liisa Matti This program prints to the screen with the document.write command Liisa Matti The first character of a variable can be a letter or an underscore.
JavaScript Variables Example For example x y and z are according to the previous example variables that can receive for example numerical values. Variables are initialized var x var y z x y JavaScript variable naming var Variable var Variable var Variable_ var_Variable Defining JavaScript variables When defining JavaScript variables values are declared for the variables Variables are typeless in the JavaScript language at the definition stage. In order for the JavaScript handler to distinguish between different variables they must be given identifiers i.e. names that distinguish them from all other variables. The tags should be named in such a way that they facilitate code maintenance i.e. its readability and comprehensibility. Variables are defined that is introduced with the var keyword which can receive numeric values or character values. Variables can be named.
