Why I developed the project

When I use the vue framework, I want to clone a array and I don't want to change the original data,so I want use some function to finish this job, So I try two ways

1:Use the "clone" of underscore or lodash

2:Use the "slice(0)" of JS

Both of these two function were failed. After that I find a solution: JSON.parse(JSON.stringify(object));

run

npm install

test

npm test
