How many variations can be produced by obfuscating a single line of JavaScript code: 'var a=1'?

Confusing code is a technique used to make it difficult to understand and reverse engineer, often employed to protect the confidentiality of source code. For a simple variable assignment like var a = 1;, here are some possible methods:

Using Uncommon Variable Names:

var _0x1234 = 1; 

Using Computational Expressions:

var a = 0 + 1; 

Or a more complex one:

var a = Math.floor(1.0); 

Using String Parsing:

var a = parseInt("1", 10); 

Using Array or Object Access:

var _0xarray = [1]; var a = _0xarray[0]; 

Or:

var _0xobj = {key: 1}; var a = _0xobj.key; 

Using Bitwise Operations:

var a = ~(~0 + 1); 

Multiple Assignments:

var b, a; b = 1; a = b; 

Using Functions:

function getOne() { return 1; } var a = getOne(); 

Using JShaman JavaScript Obfuscator:

var a = function (s, h) { return eval(String.fromCharCode(115, 32, 94, 32, 104)); }(287630, 287631); 

Please note that obfuscating code can make it harder to read and maintain, so it should be used cautiously.
