const data = [

  {'year': 2005, 'value': 771900},

  {'year': 2006, 'value': 771500},

  {'year': 2007, 'value': 770500},

  {'year': 2008, 'value': 770400},

  {'year': 2009, 'value': 771000},

  {'year': 2010, 'value': 772400},

  {'year': 2011, 'value': 774100},

  {'year': 2012, 'value': 776700},

  {'year': 2013, 'value': 777100},

  {'year': 2014, 'value': 779200},

  {'year': 2015, 'value': 782300}

];



const bisect = d3.bisector(function(t: any) { return t.year; }).left;



console.log(bisect(data, 4));


Not matter which position I give it it always returns index 0.. it's literally the same example I've seen countless times, yet it doesn't seems to be working for me for some reason..



Any ideas?

    It returns 0 because 0 is less than all years
