How to Execute Git Shallow Clone
Provide an argument of -- depth 1 to the git clone command to copy only the latest revision of a repo:
git clone -–depth [depth] [remote-url]
You can also use git shallow clone to access a single branch:
git clone [remote-url] --branch [name] --single-branch [folder]
With git shallow clone you get fewer files. And as a result, they clone faster. Builds and feedback can be delivered quicker.
javascript '=' operator shallow copy or deep copy
// The '=' operator in javascript can serve the purpose of shallow vs
// deep copy.
// The '=' operator in javascript will assign deep copy to primitive
// data types. For example:
let a = 10;
let b = a;
b = 4;
console.log(a);
// Output: 10
console.log(b);
// Output: 4
// The '=' operator in javascript will assign shallow copies to
// non-primitive data types. For example:
let a = ['a','b','c','d','e','f','g'];
let b = a;
b.pop();
console.log(a);
// Output: ["a","b","c","d","e","f"]
console.log(b);
// Output: ["a","b","c","d","e","f"]
