我有一个JavaScript数组,如:

[["$6"], ["$12"], ["$25"], ["$25"], ["$18"], ["$22"], ["$10"]]

我将如何将单独的内部数组合并为:

["$6", "$12", "$25", ...]

我想将2D JavaScript数组转换为1D数组,以便将2D数组的每个元素连接成单个1D数组.

在这里,我正在尝试转换arrToConvert为1D阵列.

var arrToConvert = [[0,0,1],[2,3,3],[4,4,5]];

console.log(get1DArray(arrToConvert)); //print the converted array

function get1DArray(2dArr){
    //concatenate each element of the input into a 1D array, and return the output
    //what would be the best way to implement this function?
}
