javascript how to inherit object from another class code example
Example 1: override function javascript class
class newArray extends Array{
push(value) {
//execute any logic require before pushing value onto array
console.log(`pushed ${value} on to array`)
super.push(value)
}
}
var array = new newArray
array.push('new Value')
Example 2: javascript inherit function
function inherit(c, p) {
Object.defineProperty(c, 'prototype', {
value: Object.assign(c.prototype, p.prototype),
writable: true,
enumerable: false
});
Object.defineProperty(c.prototype, 'constructor', {
value: c,
writable: true,
enumerable: false
});
}
// Or if you want multiple inheritance
function _inherit(c, ...p) {
p.forEach(item => {
Object.defineProperty(c, 'prototype', {
value: Object.assign(c.prototype, item.prototype),
writable: true,
enumerable: false
});
})
Object.defineProperty(c.prototype, 'constructor', {
value: c,
writable: true,
enumerable: false
});
}
