Usage

var filledBy = require( '@stdlib/array-base-filled-by' );

filledBy( len, clbk[, thisArg] )

Returns a filled "generic" array according to a provided callback function.

function clbk( i ) {
    return i;
}

var out = filledBy( 3, clbk );
// returns [ 0, 1, 2 ]

When invoked, a callback function is provided a single argument:

• index: the current array index.

To set the callback execution context, provide a thisArg.

function clbk( i ) {
    this.count += 1;
    return i;
}

var ctx = {
    'count': 0
};

var out = filledBy( 3, clbk, ctx );
// returns [ 0, 1, 2 ];

var cnt = ctx.count;
// returns 3
