How can I remove some specific character inside an Array? for example;
var wording = ["She", "gives","me", "called", "friend"];
var suffix = ["s", "ed", "ing"];
function p {
return wording.substring(wording.substring(wording) - 1, wording.length - 1))
}
var text = wording.map(p);
console.log(text);
If one of the words being iterated over endsWith one of the strings, you can slice out the length of the found suffix.
var wording = ["She", "gives","me", "called", "friend"];
var suffix = ["s", "ed", "ing"];
const p = word => {
const foundSuffix = suffix.find(str => word.endsWith(str));
return !foundSuffix ? word : word.slice(0, -foundSuffix.length);
}
var text = wording.map(p);
console.log(text);Another approach, using a regular expression:
const wording = ["She", "gives","me", "called", "friend"];
const suffix = ["s", "ed", "ing"];
const pattern = new RegExp(suffix.join('|') +'$');
const p = word => word.replace(pattern, '');
console.log(wording.map(p));METHOD 1
var wording = ["She", "gives","me", "called", "friend"];
var suffix = ["s", "ed", "ing"];
function p(w) {
var ret = w;
suffix.forEach(s => {
if( w.endsWith(s) ) {
ret = ret.slice(0,w.length - s.length);
}
})
return ret
}
var text = wording.map(p);
console.log(text);METHOD 2
var wording = ["She", "gives","me", "called", "friend"];
var suffix = ["s", "ed", "ing"];
var text = wording
//check if any of the words end with any of the suffices min 0, max 1
.map(w => [w,suffix.filter(s => w.endsWith(s))])
//use the returned array to remove suffix, if found
.map(([w,s]) => s.length ? w.slice(0,w.length - s[0].length) : w);
console.log(text);
