JavaScript Enumerations Printing an enum variable
Example
After defining an enum using any of the above ways and setting a variable, you can print both the variable's value as well as the corresponding name from the enum for the value. Here's an example:
// Define the enum
var ColorsEnum = { WHITE: 0, GRAY: 1, BLACK: 2 }
Object.freeze(ColorsEnum);
// Define the variable and assign a value
var color = ColorsEnum.BLACK;
if(color == ColorsEnum.BLACK) {
console.log(color); // This will print "2"
var ce = ColorsEnum;
for (var name in ce) {
if (ce[name] == ce.BLACK)
console.log(name); // This will print "BLACK"
}
}
