fill map javascript code example
Example 1: js array fill map
let filledArray = new Array(10)
.fill(null)
.map(()=> ({'hello':'goodbye'}))
// In this approach, we are creating an array with ten empty slots,
// then filling those slots with the null value,
// then creating a new array with unique objects.
// Now when we change an object in the array,
// we are only changing a specific object, not a reference to an object.
Example 2: array js fill
let filledArray = new Array(10).fill({'hello':'goodbye'});
Example 3: new map js
let utilisateurs = new Map()
utilisateurs.set('Mark Zuckerberg' ,{
email: '[email protected]',
poste: 'PDG',
})
utilisateurs.set ('bill Gates',{
email: '[email protected]' ,
poste : 'sauver le monde' ,
})
console.log(utilisateurs);
