Someone asked me what is the difference between {} and [] within javascript.
Basically the difference is one is a key => value pair like PHP ‘{}’, and the other is just a pure array of values ‘[]’.
Here is the code.
var simplearray = ["genux","linux"]; var keyvaluearray = {"name" : "genux", "OS" : "linux"}; |
To access the different values, since the simple array is index by numbers 0 onwards you use the [x] notation, and the key value array you can reference the value by the name of the key like in object orientated way.
alert(simplearray[0]); alert(keyvaluearray.name); |
