我想用 for 循環(huán)創(chuàng)建下面的數(shù)組作為它的大var centres = {    1979: { x: width * 1 / 41, y: height / 2 },    1980: { x: width * 2 / 41, y: height / 2 },    1981: { x: width * 3 / 41, y: height / 2 },    ...}然后按如下方式訪問它：function nodeYearPos(d) {   return yearCenters[d.year].x;}我有以下代碼，但它只設(shè)置年份......  var yearCenters = Array.from(new Array(2020-1919+1), (x, i) => i + 1919);  for (year = 1919; year <= 2020; year++) {    coords = getCentres(year); // this returns an object in the form {x : x, y : y}    yearCenters[year] = coords;  }
