TIL: Creating Globals
#programming
#javascript
Today I learned you can create globals by passing unnecessary arguments to a function in javascript.
For example:
function myFunc(a) {
console.log(a);
}
myFunc(123, (i=100));
console.log(i);
Calling this function with that second argument expression will assign
a global i
to the value 100.
