    capitalizeKeys

    NPM version Build Status Coverage Status

    Convert the first letter of each object key to uppercase.

    Installation

    npm install @stdlib/utils-capitalize-keys

    Usage

    var capitalizeKeys = require( '@stdlib/utils-capitalize-keys' );

    capitalizeKeys( obj )

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

    var obj1 = {
        'beepBoop': 1,
        'fooBar': 2
    };
    
    var obj2 = capitalizeKeys( obj1 );
    // returns { 'BeepBoop': 1, 'FooBar': 2 }

    Notes

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

    Examples

    var capitalizeKeys = require( '@stdlib/utils-capitalize-keys' );
    
    var obj1 = {
        'aa': 'beep',
        'bb': 'boop',
        'cc': 'foo',
        'dd': 'bar'
    };
    
    var obj2 = capitalizeKeys( obj1 );
    
    console.dir( obj2 );
    // => { 'Aa': 'beep', 'Bb': 'boop', 'Cc': 'foo', 'Dd': 'bar' }
