globalConst()

Define a global read-only, hidden property.

Syntax

try {
  globalConst(sName, vVal);
} catch(e) {
  // likely a TypeError if an existing non-configurable property of the same sKey is defined
}

Parameters

Parameter	Type	Mandatory	Description	Util.js version
sName	String		The name of the global constant reference	0.8
vVal	Variant		The value associated with the constant reference	0.8

Return value

If a non-configurable property of the same name is already defined, an error will likely be thrown.

Example

Same as using 'const' declaration in global scope

globalConst("foo", "bar");
 
// same as:
const foo = "bar";

Create global constant from within a function

function wibble() {
  const foo = "bar"; // error; in future might create const within scope of wibble()

  globalConst("foo", "bar"); // creates global "foo" constant with value "bar"
}

Availability

This feature requires:

Util.js v0.8 and above
