example

javascript:

(async function () {
    var netCDF4 = require('./index')
    var path = require('path')
    var ds = new netCDF4.Dataset()
    var ncOrHdf5FileName = path.join(__dirname, 'sampleData/FY4A-_AGRI--_N_REGC_1047E_L2-_CTT-_MULT_NOM_20190210073834_20190210074250_4000M_V0001.NC')
    await ds.readFile(ncOrHdf5FileName).catch((err) => {
        console.error(err)
        throw err
    })
    var subDatasets = ds.subDatasets();
    var variable = await ds.readVariable(subDatasets[0]);
    console.log(variable) 
    console.log(variable.get(0, 10)) 
    console.log(variable.minMax); //variable.attributes['valid_range'] 
    ds.close();//Close dataset，exit python process，delete temporary  files
})()

print：

Variable {name: "CTT", attributes: Object, dataType: "float32", shape: Array(2), data: Float32Array(3044784), …}
