角度6应用中的Js。它在Chrome，Edge和Firefox中正常工作。 IE中的错误。

SCRIPT1010：预期的标识符 vendor.js（290527,19）

在进一步调试中，它显示

处的vendor.js错误

// get all points within the passed range
function range ( ...args ) {
    let options

    if (isObj(args[args.length - 1])) {
        let arg = args.pop()

        // detect if that was a rect object
        if (!args.length && (arg.x != null || arg.l != null || arg.left != null)) {

当将Plotly与webpack一起使用（Angular CLI在内部使用）时，需要ify-loader（Webpack加载器按预期处理浏览器转换）。我改为使用@ angular-builders / custom-webpack：browser构建器，并将其添加到解决了该问题的webpack配置中。

main()
{
    # initialize grid with Integer.MAX_VALUE or just a big enough number
    # for Cell in Cells -> put obstacles on Grid as -1,
    #                      find the Start and Goal and record them somewhere
    # DFS_plus(array, Goal, 0);
    # FindPath(list, array, Start);
    # Done
}


void DFS_plus(array, row, column, distance):
    if(array[row][col] <= distance) return; # There already exists a shorter path there
    # or it's an obstacle, we store obstacles as -1. 
    # It's smaller than any possible path and thus blocks further search

    array[row][column] = distance; # update distance.
    # If this happened its neighbors will need to be updated too.

    #Check for edge cases, or initialize array to be bigger and place obstacles on edge#

    DFS_plus(array, row-1, column, distance+1); # You just map everything, no returns expected
    DFS_plus(); # For all 4 directions
    DFS_plus();
    DFS_plus();
}

FindPath(list, array, row, col){
    if(array[row][col] == 0) return; # It's the Goal

    if(array[row-1][col] == (array[row][col] - 1)){ # Check if Cell above is 1 closer to Goal
        list.add("MoveUp");                           # Add direction
        FindPath(list, array, row-1, col);          # Look for next direction
        return; # You don't need to check other directions as path is guaranteed
    }
    if(){}; # Check other directions if Up wasn't the one
    if(){};
    if(){};
}

Plotly.Js无法使用IE。 vendor.js中的错误
