uppercaseKeys

    Convert each object key to uppercase.

    Usage

    var uppercaseKeys = require( '@stdlib/utils/uppercase-keys' );
    

    uppercaseKeys( obj )

    Converts each object key to uppercase, mapping the transformed keys to a new object having the same values.

    var obj1 = {
        'a': 1,
        'b': 2
    };
    
    var obj2 = uppercaseKeys( obj1 );
    // returns { 'A': 1, 'B': 2 }
    

    Notes

    • The function only transforms own properties. Hence, the function does not transform inherited properties.
    • The function shallow copies key values.

    Examples

    var uppercaseKeys = require( '@stdlib/utils/uppercase-keys' );
    
    var obj1 = {
        'a': 'beep',
        'b': 'boop',
        'c': 'foo',
        'd': 'bar'
    };
    
    var obj2 = uppercaseKeys( obj1 );
    
    console.dir( obj2 );
    // => { 'A': 'beep', 'B': 'boop', 'C': 'foo', 'D': 'bar' }
