This article is taken from JavaScript @ Wikibooks. JavaScript is a loosely typed language, this means that you don’t have to worry about setting the type of variable and you can change at will in runtime. But when you code, you have to make sure that you are getting the right type at the right time. Variable declaration Variables are commonly explicitly declared the var statement, as shown below: var c;
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; } The above variable is created, but has the default value of undefined. To be of value, the variable needs to be initialized: var c = 0; Variables can also be created by assigning directly to them,...
