一套前端设计语言和基于React的实现

function cmp(a, b) {
    if (a < b) {
        return -1;
    }
    if (a > b) {
        return 1;
    }
    return 0;
}
export function getPotentialValues(marks) {
    if (!marks) {
        return [];
    }
    return Object.keys(marks)
        .map(function (it) { return Number(it); })
        .filter(function (it) { return !Number.isNaN(it) && it !== Infinity; })
        .sort(cmp);
}
export function normalizeToPotentialValue(potentialValues, value) {
    var i = 0;
    var j = potentialValues.length;
    while (true) {
        var p = Math.floor((i + j) / 2);
        if (j === i + 1 || p === i) {
            if (Math.abs(potentialValues[i] - value) <=
                Math.abs(potentialValues[j] - value)) {
                return potentialValues[i];
            }
            return potentialValues[j];
        }
        var mid = potentialValues[p];
        if (value === mid) {
            return mid;
        }
        if (value < mid) {
            j = p;
        }
        else if (value > mid) {
            i = p;
        }
